What if

This is something I have thought about a lot lately. What if I would have done this or that, what if I hadn't done what I did. Fairly useless thoughts, but indeed those that occupy my mind now and then.

What if I didn't say or do that back then, I wouldn't be here. What if I had done differently, had I still ended up where and who I am today?

Impossible questions, and no real answers. Why do I spend time on this?
