You tried a side of yourself that now you don't like.* Like
   +[1]Richard Hernandez* said - it's learning. If you always did
   everything right, you might never know when you've done
   something wrong. Cliche?* Sure.* But it's also true.* Sometimes
   a mistake leaves a little annoying reminder inside of you: "Hey,
   psst, remember the time you did that thing?* Remember how you
   felt afterwards?* Yeah, this thing you're about to do? It's just
   like that time.* Do you REALLY want to go through that again?"
   and so it becomes one of the bits of your conscience and helps
   you make decisions throughout your life. Personal evolution.*
   This stuff is a part of it.* It's like Pokemon evolving except
   you get many more evolutions.* I've probably had dozens of
   evolutions - old "me's" that I look back on and go, "Oh yeah, I
   remember when I thought that was a good idea but I've improved
   now".
