By your 40s, most of the tumultuous, world-rocking changes are behind you. On one hand this means you'll probably never become president, an astronaut, or an Olympic downhill skier. But you're good at what you do. And you know who you are. And the rest doesn't matter so much. I sing in a rock band. I bake amazing blondies. I throw a kick-ass fundraiser that raises beaucoup bucks. I also have insanely frizzy hair, I'm horrible at math (see above), and I've given up on trying to enjoy classical music concerts (sorry, Dad). But I'm good at what I do. I know who I am, and the rest doesn't matter so much.
