As for the post-it/to-do lists, what helps me is to develop a point system (scale of 0~5 or whatever) and assign a point next to a criterion at the end of the day, depending on how well you think the task was accomplished. It works even better if the tasks are something that's repeated weekly (e.g. organisation of your living space), as you'll end up with a collection of points.

While easy and non time-consuming, it's powerful in a way that it creates a feedback process. Of course, there's bunch of different reward systems people use besides scoring high points, like earning oneself a cigar, for example. So you can develop one that suits you for more fun.
