Here is an excerpt from my book, The Silent Master: Awakening the Power Within:
Usually there is an all too human tendency to give in to your past, unwanted Self-Concept even while you're trying to change it. When it comes time to let go of Self-Concepts like I'm an angry person, I'm a worrier, I'm a sad person, I'm a sick person, I'm a “workaholic, or even, I'm a doctor, I'm a waiter, or whatever, this may feel like a supreme sacrifice. Since your present self is all you know, you may feel like the sacrifice of your undesirable traits, whatever they are, is a loss, not a gain. You may feel you're losing yourself.
