Think about your average day when you've succeeded in your goal or reached your dream. What does it look like? What do you do in the morning, the afternoon, the evening? Get specific!

I'm short, if it's your dream, or you're waiting until something like retirement to do the things you've always wanted to do, why not start them right now; what's stopping you?
