I've got that at the moment at work - and although I know I should be happy to have so many good things available to me, in fact I'm feeling physically sick about having to make a choice. It doesn't help that I'm then also feeling bad about not just being happy.
I've tried pros and cons, I've had coffee with a trusted friend, I've taken advice, perspective (and a bit of coaching) from my boss and several other senior people I trust. Some people helped me identify more options, some people helped me get clearer about what matters. I was advised to plump for one option (but not tell anyone) and see whether my guts felt it was right or not. I got taught to use BRAINS (benefits, risks, alternatives, instinct, could you do nothing, and then smile about whatever decision you end up taking) to make a decision.
I'm fairly sure that most of the outcomes will be good. And still I'm sweating it. Have you ever faced this kind of thing? What would you do?
