Unconditional Self-Acceptance (USA) is not achievement-dependent. USA depends only upon taking a realistic look at yourself and accepting that this is where you are right here, right now in your life, without judgment. Having thus accepted yourself for all of your current traits, good, bad, and neutral, you are in a position to realistically assess what you would like to change about your current behavior. Acceptance is not complacency. Accepting yourself as you are does not mean stopping there, but it allows you to comfortably re-assess without putting yourself down for this lack or that failure. It is what it is, and accepting that without negatively judging yourself, versus judging a given behavior, is what gives you the motivation to alter it.
Unconditional self-acceptance provides you with power; the power to change. The reverse of USA is NOT self-hatred; it is simply denial. Thus, if you have not yet achieved USA, this simply means you have not yet given yourself a good, hard look and accepted each and every part of you: looks, behaviors, thoughts, and feelings. Some of these are malleable, and some are fixed. You cannot change your height, but you can change your mood or how you react to your failure to make that golf shot or your tendency to eat late in the evening. You begin with completely accepting that unfavored behavior and examining the thoughts that drive it. With this non-judgmental approach, it is much easier to take on the challenge of making difficult changes.
