Beliefs Shape Reality

I’m a big believer in the power of belief. In my upcoming book, Being Well, I explore how our mindsets about our current and future selves impact our ability to change and sustain healthy behaviors.

In his new book, Beyond Belief, Nir Eyal makes a similar argument: our beliefs about what is possible are the foundation of motivation. Limiting beliefs often lead to failure not because we lack ability, but because we quit too soon. Liberating beliefs, by contrast, fuel sustained action and growth.

Eyal identifies three key ways beliefs shape behavior:

1)    Attention

Beliefs determine what we notice and what we filter out. We see reality through the lens of our beliefs. When you look for evidence that challenges a limiting belief, new opportunities and solutions come into view. For example, if you believe your mother is over critical, you may interpret many of her comments as criticism. Questioning that belief can help you notice appreciation and understanding that were always there but filtered out by your assumption.            

2)    Anticipation

What we expect influences how our minds and bodies respond. When people believe a wine is expensive, their brains’ pleasure centers light up more strongly. When individuals believe they’ve consumed caffeine, even when they haven’t, they perform better on attention tasks. Placebos can trigger the release of endorphins, the body’s natural painkillers. Mindsets can also influence aging, performance, and stress responses.

3)    Agency

Beliefs determine whether we persist or quit. We keep going only if we believe our efforts will matter. Belief in our capacity to handle obstacles motivates action, and seeing evidence that our actions make a difference strengthens our sense of agency.

Beliefs are not truths; they are tools that can be tested, refined, or replaced when they stop serving us. Belief-building is a skill that can be strengthened over time. The first step is identifying your limiting beliefs. When do you feel doubt or become self-critical? The next step is replacing those beliefs with more liberating ones that support action and growth.

You have the power to direct your attention toward what serves you, to anticipate possibility rather than limitation, and to take action. In my own life and the research I did for Being Well, I’ve learned that questioning a limiting belief is often where change begins.

Think of one area where you feel stuck, a health habit, a relationship, a goal you’ve abandoned. Ask yourself what belief is driving your behavior and question whether it’s actually true.
