"The novelist Norman Mailer wrote in The Deer Park, it's a law of life that "one must grow or else pay more for remaining the same."
So true, though many people believe that who you are - specifically, your personality - is fixed. In fact, much conventional thinking in psychology holds that our personalities remain constant.
But that's not accurate: We're always changing and evolving, in some way - for better or for worse. Many of us mental health professionals witness that occur among our patients. Keep in mind that who we may "become" is being shaped and determined by who we are right at this moment, by the kind of person we are inside; the qualities that we express in our daily lives, relationships and aspirations."
