When I have a personal problem, I find it very helpful to write a letter to an advice columnist in my head. Almost always, you know what you should do to solve a problem but don't want to recognize it. Thinking through how you'd frame the issue to an uninformed third party usually lets you know what the answer must be: what are you going to special trouble to avoid? what course of action are you attempting to justify to yourself, and what are you trying to play down?
Of course, the one time I actually asked for advice from strangers, they gave me a completely new and previously unconsidered take on the situation which ended up being correct, so maybe this not as effective as it might be.
