"The whole fake-it-till-ya-make-it thing is BS — it's be it till you become it."
How to develop neuroplasticity is about asking yourself how you can create your best self. You are building an identity with every action that you take. Building your identity is a lifetime endeavor. As you are practicing building your core identity (who you know yourself to be, who you strive to become), you will inevitably try new ways of being, you'll succeed and you'll fall down and get back up and try again. Regardless of the outcomes in your life, know that you are doing the best you can. Have the wisdom to know the difference between the things you can change and the things you cannot (serenity prayer). What you're ultimately committed to is the process and practice of becoming a better and better version of yourself.
