"I never knew anyone who went crazy before, except for my imaginary friend Captain Sprock!" - Chris Griffin, Family Guy
Here's a quick tip: when you're struggling to reach a decision, imagine that a friend is asking you the question you want answered. You can use a real friend for this but I prefer to use an imaginary friend as they generally come with less luggage. Sometimes this helps change your mindset, and distance yourself just enough from the problem, that you can come up with a solution.
