change my thinking

Ok, ok….I know that in order to improve my self esteem and all these other goals on my list, I’ve gotta find some way to change my thought process. How do I just “become” optimistic? Hmmmm, I’m gonna spend this weekend (wait, wait, lemme rephrase…”try to spend this weekend…”) working on changing my thinking. Basically I’m a “glass is half-empty” kind of person….but I’m gonna try to be “glass half-full”......at least for a day, lol…
