According to Chip and Dan Heath, co-authors of the book Decisive:How to Make Better Choices in Life and Work, the key to making good decisions quickly is to pretend you are someone else.
For personal decisions the questions is “What would I tell my best friend to do?”
For work decisions the question is “If I were replaced tomorrow and a wise successor took my place, what would he or she do?”
They say something profound happens when you look at your dilemma from the outside.
