Change is never comfortable. However, with work and practice you can train yourself to semiautomatically remain minimally disturbed for the rest of your life. Train yourself to see that rejection is sad but not a holy horror. See that to error is human and strive to learn from mistakes and erroneous assumptions. Push yourself to think flexibly and always accept yourself regardless of how imperfectly you perform or who may reject you.
