I've had a little of the muddling/transferring/obsessing and it has been worth it for me. A little of being obsessed, over a period of a few months or so, let me take it seriously enough for it to make a difference. I think that if you're aware of those possibilities ahead of time, it can help you know what's going on if it starts to happen, which would make it easier. Also, there's nothing to prevent you from deciding to quit at any point.
