The days are long but the decades are short

Work very hard—a surprising number of people will be offended that you choose to work hard—but not so hard that the rest of your life passes you by.  Aim to be the best in the world at whatever you do professionally.  Even if you miss, you’ll probably end up in a pretty good place.  Figure out your own productivity system—don’t waste time being unorganized, working at suboptimal times, etc.
