What should I get up at 0400 every day?
Well, success should be a good motivational factor. Once you define your meaning of success, it becomes the why to do what ever it takes to move forward toward it. The drop off to do it is so present, pulling you over the cliff minute by minute, so you have to be ankle to avoid being dragged over the visible cliff just behind you.
Creativity takes effort you can monster by diversifying your daily life. Get off the routine by pushing yourself to do new events on a weekly base. New sport, an active engagement on a sport, not watching it on an electronic device. New people, those away from your normal work environment. New sites and people to engage and listen to. New instrument, one you will master over time. New hobby, got the point?
