The best advice I have been given is to live in the moment, as cliché as that sounds. It's crazy.
To live in the moment is truly an art and is truly a talent, because when you live in the moment then you are truly the master of your whole life and you'll have the best times.
Instead of thinking about work the next day or thinking about what you have to do, if you live in the moment you'll have some of the best times of your life.
