A huge part of losing weight, getting fit, and staying that way is learning to break your old bad habits. We may all know what we're supposed to be doing for a healthy lifestyle, but most of aren't following through -- not really anyway.

So start by sitting down with a notebook and jotting down some of the things that you know get in the way sometimes. When do you feel guilty? That's probably one. Next, analyze yourself and think of what might help you get past it next time it crops up: make a battle plan.

And last, hand pick some new good habits you're going to work on. Whether it's stuff you're already doing that you want to be better at, like eating breakfast every day, or something you haven't done yet at all but should, like starting a walking program, write it down and really work at doing it regularly. If you stick with it through the starting "rough patch" it will eventually become habit, and second nature.
