> Maybe 10 years ago, I had solid answers to all of these, but now I don't.

My experience is that as I get older I get less certain about many things, not more. I think this is mainly due to experience teaching me about the complexities that can hide below the surface of seemingly simple things. My younger self didn't know this - which is ok as he had other things to do.

So it is possible that you just know yourself better than you did ten years ago, and that's the reason that the simple questions about yourself don't have simple answers anymore.
