Neuroscience confirms that your personality creates your personal reality. Your thoughts, behaviors, habits, and emotions form your identity, shape your brain, and show up in your body. In You Are the Placebo: Making Your Mind Matter, Joe Dizpensa writes:

Ninety-five percent of who you are by the time you’re 35 years old is a set of memorized behaviors, skills, emotional reactions, beliefs, perceptions, and attitudes that functions like a subconscious computer program.

It’s commonly said that most of the thoughts you have today are the same ones you had yesterday and that the conscious mind’s small capacity is constantly working against this predominant unconscious programming, which is largely made up of wounds, fears, and negative memories and experiences from your past.

To change the automatic, subconscious script playing in your head will feel like trying to swim upstream at first, but with persistence and time, it can be done.

If you want to change the way you feel, you’ve got to change the way you think.
