OHHHHHHH man, I think this would be a great thing for all of us to remind ourselves of every morning before we start the day. Imagine going into work, even if that's staying home with kiddos, with this on your mind?
One of the keys to success is passion. If you care about something or want it naturally you won't need to force yourself to work on it. The passion will be your fuel. Only work on things you are passionate about.
