Thoroughly agree.
I've always been comfortable with decision making and responsibility, but I was a very poor planner and risk assessor before I did my PPL.
I would never write anything down and was terrible at filing anything.
I would never make any decision until the last minute, although I would always be able to make one, and mostly be happy with it, whereas now I make decisions much sooner and everyday things become much less frantic than they used to be.
I also drink a lot less than I used to as I'm absulutely useless the day after a few beers/wines.
(Although I'm still on the fence as to whether this is a good thing or not!)
