In some fields the winner takes it all. Either you win or you die.

Also money is like a drug. What's wrong with taking a little cocaine in the morning and a little heroin in the evening? Nothing, except there are very few people who can sustain that over an extended period of time. You also wouldn't know about them because they neither become very rich nor very famous. ("Hey look there is the most average guy in the whole country who has no exceptional qualities.") The world belongs to the candles who burn from both ends.
