A real problem you may encounter when you are trying to change your life often comes from old friends and family who only know and accept the "older you" and not the person you are striving to become. A lot of people are not really evolving themselves, and some of these people don't like it when they see someone from their social peer group advancing, and maybe even doing better than them. So, these people will sometimes be quick to point out something negative you may have done in the past, or they may bring up a negative behavior when you "slip-up" while you are working on yourself. Sometimes these people can even encourage the old negative behavior you are trying to eliminate, because they enjoy that part of you, or they may even secretly, or sub-consciously, want to see you fail. You want to avoid all messages that reinforce your old patterns, whether those reinforcements come from yourself, or from others.
