What is the point? The point is you - live your life, make your own successes & failures, find your own path regardless of other people's opinions, so you have no regrets- you own it all. Celebrate life, and keep marching on when you can't.
I always liked that song by Seal, 'Crazy', and as I get older I think being totally rational can be overrated,.
Maybe it is best to be a little crazy.
