You can't change what you don't measure. Want to get rich? You need to have more money coming in than going out, it's as simple as that. If you don't keep track of how much is coming in and how much is going out, you'll never get there.

You're presenting a false dichotomy. Personal accounting does not preclude personal growth. It takes about an hour maybe to set up mint to track your account and maybe a few minutes every couple weeks or once a month to look at it and see where you are. There's plenty of time left to work on growth.
