Bottom line if you want success of any kind: you have to be comfortable being uncomfortable. Every time you think you can’t, you have to do it anyway. That last mile, the last set, the last five minutes on the clock. You have to play the last game of the season with the same intensity as you played the first. When your body is screaming and depleted and telling you, ‘No way asshole,’ you work harder and tell yourself, ‘Do it. Now.’
