For me, I'm guessing "Curmudgeon" is on the menu at some point. :)

Age brings perspective. One would hope it also brings growth, but there are plenty of people who choose to do things a certain way because they've always done them. The "progress optional" ones.
Along the way I think I've been at least 6 different people. Some of them I look back on and don't like all that much. I suppose I have a couple more changes coming.
At least I hope so.

I hope so, too. unfortunately, some of us learn without applying our acquired knowledge (something I can relate to at times), but in the best case scenario, I imagine most of us are due for more changes. hopefully.
