I sought out the best players and the best games that I could find. I took a lot of lumps along the way, in order to improve. That's what I did to get to the point where I won championships. All of those lumps/losses didn't make me a loser. It made me a champion.
Were you an NBA champion? If not, why? You know what you would be if you dedicated your entire life to becoming an NBA champion? A loser.
