Deep down, many of us feel that we’re not as happy as we could be:

• We feel stuck living a life we don’t want.
• We feel ashamed of past mistakes, uncertain of how to let them go.
• We worry about the future and feel crushed by all the anxiety it brings.

Unfortunately, simply understanding that you’re unhappy isn’t enough — you need to understand the root cause of your unhappiness to move on with your life.

While I don’t claim to understand everybody’s unhappiness, my work as a psychologist has given me some insights into the basic patterns of unhappiness.

But these patterns can be difficult to see because they exist on a barely conscious level — the level of core beliefs.

Core beliefs are rules or operating instructions for our lives.

They’re often established very early in childhood and rarely identified or updated, which means we end up carrying them into adulthood, along with all the emotional baggage they contain.

In the rest of this article, I’ll introduce you to three of the most common core beliefs that are at the root of many people’s unhappiness. If you can learn to identify them in your own life, it’s possible to find a level of happiness you may never have known possible.

Here are 3 core beliefs that make you unhappy:

1. I need to feel good to do hard things.

Motivation is a funny thing. When you’ve got it — when you’re energized, enthusiastic, and really “feeling it” — it’s like you can do anything:

• Go for a run at 5:00 a.m.? No problem!
• Learn to play guitar? Let’s do this!
• Order a kale salad for lunch instead of that burrito. Done!
• Make some serious changes to my marriage? Yes, I’m up for it!

But, when you’re not feeling motivated — when you’re feeling sluggish, lazy, and apathetic — it’s as if you can’t do anything:

• Getting out of bed and into the shower feels like a Herculean effort of will.
• Learning guitar is a pipe dream I should have given up years ago.
• Not only am I getting the burrito, but I’ll take extra guac, some chips, and that fudge brownie too.
• And as for my marriage… What’s the point? It’ll always be like this.

For better or worse, motivation is a powerful force in our lives. It can push us to achieve our wildest dreams and its absence can discourage us from taking even the tiniest step toward them.

But here’s a little secret most people don’t know:

Your motivation problem has nothing to do with motivation itself and everything to do with your beliefs about what motivation is.

Most people believe motivation is a gift — something the universe generously bestows on us from time to time, and more frequently, withholds. They believe that with this gift, they’re capable of great things. But without it, they’re destined for mediocrity or failure.

Of course, occasionally we do indeed feel “hit” by motivation and unexpectedly energized to take difficult action. But this is only part of the story.

The relationship between motivation and action is a two-way street: Feeling good makes it easier to accomplish hard things. But doing hard things leads to feeling good.

Happy people believe that motivation is built not bestowed — that’s it’s something largely under their control.

They know that the best way to accomplish their most important goals and aspirations — from losing weight to building a satisfying marriage — is to generate a steady stream of motivation for themselves by doing difficult but meaningful things regardless of how they feel.

As you’re reading this, you’re probably thinking to yourself:

Yeah, yeah, that sounds like a nice idea — and sure, maybe it’s true — but at the moment, it’s just too hard. I tell my body we’re going for a run this morning, but my body says “Like heck, we are!” and rolls back under the covers.

I get it: understanding all this isn’t going to change anything. And that’s because changing your core belief about the nature of motivation isn’t fundamentally an intellectual problem; it’s an experiential one.

You need to prove to yourself that it’s possible to do difficult things without feeling motivated. And like any difficult challenge, you need to start small and work up, gradually building your confidence along the way.

Here’s an example:

Let’s say you want to work on exercising first thing in the morning. Trying to jump out of bed and go for a 3-mile jog right off the bat is probably not a great idea. Instead, just focus on getting up 15 minutes earlier than usual — don’t even think about exercise at this point. Simply prove to yourself that you can consistently get out of bed a little earlier than planned.

Once you can do that, get out of bed 30 minutes earlier. Then move on to doing 5 pushups first thing in the morning. Then 3 sets of five. Once you’ve got that down, try going for a walk for 10 minutes around the block each morning. Then 20 minutes. Once you’re doing that, mix in a couple of 5-minute segments of jogging into your walk. You get the idea…

Happy people set challenging goals and work toward them regardless of how they feel. And they’re happy precisely because of their belief that motivation follows action, not the other way around.

If you want to be happier, don’t wait around for motivation to strike. Learn to build it yourself.

2. I need to be tough on myself to be successful.

Many people grow up believing what I call the Drill Sergeant Theory of Motivation.

This is the idea that to achieve anything significant in life — from good grades to football championships — we have to be tough on ourselves. And usually, this takes the form of harsh and judgmental self-talk:

• After getting an A- on a test instead of the A+ you hoped for, you immediately kick yourself: I knew I should have studied for that extra hour. I’m so lazy. I better get my act together or I’ll never get into MIT.
• While prepping for an interview for a new position at work, you say to yourself: You better not screw this up. This position only comes up once every few years. Don’t say anything stupid!
• Following a rough day with the kids, you start berating yourself for being a lousy mom: Why can’t you just be a little more patient with them?! If you were a better mom, they probably wouldn’t be acting out so much and all of this would be way easier.

When your core belief is that success only comes from being tough on yourself, it’s easy to fall into a habit of negative self-talk and all the depression, anxiety, and misery that goes with it.

But here’s the thing:

Successful people are successful despite their negative self-talk, not because of it.

How do I know this, you say?

For years in my job as a therapist, I’ve been working with high-achieving folks who believe unfailingly that they need to be hard on themselves or else they’ll “lose their edge.”

But the price they pay for this belief is steep: A near-constant inner monologue reminding them of how they’re not good enough and never work hard enough, which is crushing them with anxiety and stress.

The solution for these people is the same: I encourage them to experiment (in small ways at first) with giving up this belief that if they’re not hard on themselves they’ll stop achieving and being successful.

The results are striking:

Never once have I seen someone perform worse because they stopped beating themselves up.

The vast majority of the time, their performance (and happiness) increases sharply!

They realize that not only are their fears of “losing their edge” unfounded, but actually, they have much more energy and enthusiasm to channel into their work and lives when they’re not stuck under the weight of chronic self-judgment.

But as is true of all core beliefs, letting them go is not an intellectual problem; it’s a behavioral one. To change your core belief about success, you need to prove to yourself that you will still be successful without your inner drill sergeant.

But for many people, that’s a terrifying idea. Because for years this core belief has served as a kind of safety blanket, assuaging their fears of being unsuccessful or not good enough. To take it off and strive for success without it requires a great deal of courage.

And courage has to be built — slowly and gradually over time.

So start small. Try thinking of little experiments you could run to test out this idea that you’ll remain successful without all your negative self-talk and self-judgment. For example, you might go into that weekly sales meeting Monday morning without any of your usual “pep-talking” and see what happens.

A sign of emotional maturity is that we let go of old habits that no longer serve us well, no matter how much we thought we needed them as children.

Let go of the belief that you must be hard on yourself to be successful and you’ll find happiness not far behind.

3. I need to be successful to be lovable.

Of all the destructive core beliefs that hold us back from happiness, this one is the most tragic — and possibly the most common.

For all the very real benefits of living in an achievement-oriented culture, there’s a serious psychological side effect most of us don’t ever consider: We tend to bind our self-worth to our success — especially our material success as defined by other people.

From cradle to grave, we’re taught that hard work pays off and will lead to success and then happiness. We’re nudged by all sorts of well-intentioned family members, teachers, friends, and mentors to go to the right schools and get the right career so we’ll become successful and then happy. The problem is, as kids, we internalize this message to mean — however irrational — that we’re only worthwhile and lovable if we’re successful.

Working hard to be successful is an admirable aspiration. However, believing happiness only follows success is deeply misguided.

This is a truly tragic way to go through life — believing that you’re only worthwhile if you’re successful.

Every day in my clinical practice I work with many materially successful people who believe becoming successful is the only way to be loveable and happy. But being a neurosurgeon doesn’t make you very happy if you hate being a neurosurgeon — no matter how many other people think it’s impressive.

While achievement certainly plays a role in our happiness and self-worth, it’s dangerous to depend on it entirely. When you’re so driven and obsessed with achievement that you fail to develop other sources of self-worth, you fragilize your identity.

The solution is not to stop working hard. It’s to diversify your identity.

You wouldn’t put all your retirement savings into a single stock because if that one company fails, there goes your retirement. Instead, you diversify: you put money in bonds, index funds, maybe some real estate, maybe invest in some private business, etc.

Genuine and lasting happiness comes when we have a robust and flexible sense of self. One that’s fed and nourished by a variety of “income streams.” And while your success or performance in your work may be one valuable source of identity income, don’t let it be the only one:

• Cultivate meaningful friendships.
• Develop a passionate hobby or side project.
• Make time to give back, volunteer, or mentor those who are less fortunate.
• Become active in a cause, charity, or political organization you believe in.

The possibilities for self-worth are limitless. The only mistake is not to explore them.
