There's a couple of rules that I have been following, more or less consciously, for the past few years: 1) Seek advice from people you respect. 2) Don't let fear take your decisions for you: Will you regret (not) doing this? 3) If you're thinking about taking a risk: How bad is the worst-case scenario, and how likely is it? Even if it's bad: Would it be worse not to have tried? 4) Think through your options carefully, but recognize that for many decisions, you will never reach absolute certainty. Learn to live with the concept of sufficient certainty. 5) Take a decision and run with it. Don't keep second-guessing yourself. Learn from your mistakes, but don't beat yourself up about them, especially if they were only evident in hindsight.
