After the game, the kid thinks about what worked and didn't and why. Even if every experiment failed, the next time he will be a better basketball player. If the kid went out and had one or two beers after the game, all of the analysis of the new moves would be distorted. It would be almost like never playing the game at all. The kid won't be a better player just because he was high right after the game.
Life is like that.
Teachers bother you. Boyfriends and girlfriends break up. Bosses are rude to you. In life you try to handle these situations. Some things work and some things don't.
