A few years ago, a friend told me these very useful questions that help when trying to make a decision:
What will happen if you do X?
What won’t happen if you do X?
What will happen if you don’t do X?
What won’t happen if you don’t do X?
Thinking about these questions lets me clarify my thinking and sort out the consequences of chosing one option over another; and helps me move out of the ‘Arrghh, do I really have to make a decision, can’t someone else do it, why do I have to be a grown-up’ cycle, that can immobilize an otherwise rational and competent adult. (This does happen to other people – it’s not just me, right?)
