I think this is good advice (don't just try to exercise your willpower, change your surroundings), and it holds for making good habits as well. If I want to start doing daily exercise, it's not likely to work if I just wake up at six and try to will myself to do it. Make an appointment to play tennis with somebody the day before--then you're socially obligated to show up. Do it frequently enough, and pretty soon you'll know a bunch of people who also play tennis; they'll start making appointments with you to play. Is this a "habit"? Or is it just a natural outcome of the environment you've surrounded yourself with?
