Take the stupidest thing you've ever done. At least it's done. It's over. It's gone. We can all learn from our mistakes and heal and move on. But it's harder to learn or heal or move on from something that hasn't happened; something we don't know and is therefore indefinable; something which could very easily have been the best thing in our lives, if only we'd taken the plunge, if only we'd held our breath and stood up and done it, if only we'd said yes.
