Sometimes I wish I had more characteristics of an Ayn Rand character, that by sheer force of will I could make things happen: specifically, turning myself into a better me; I know my "fixed mindset" background makes me swing too hard the other way, into strategies that avoid pointing out my deficiencies on the micro level, but make be less capable in the macro sense.
One trick I've heard lately is to replace "Oh, I really shouldn't do ___" with the thought that "I'm the kind of person who doesn't ___"; swap the verb for the noun, so to speak.
