Don't wait til you're 50 to start doing what you want to do. Now is the time.
It's time to stop going places you don't want to go and to start going to the places you do want to go.
It's time to stop doing things you don't want to do and to start doing the things you do want to do.
It's time to stop hanging out with people you don't want to hang out with and to start hanging out with people you do want to hang out with.
Personally, I decided that if I am going to live three months or thirty years I am doing the things I love to do from now on, forever.
