Ah but think about an actual (habit) problem you have had and see how many courses of action you can think of. In my experience many of them will help, and so trying in order of probability is a great way to find what might help. The just try it method pivots you from a moaning/accepting of problems attitude to: I can solve this, I just don't know how. But I know how I (probably) can find out how.

Of course it is difficult to be objective enough to identify real trends...
