Managing can be more discouraging than playing, especially when you're losing because when you're a player, there are at least individual goals you can shoot for. When you're a manager all the worries of the team become your worries.
I was an accomplished junior tennis player up to around fourteen years old. At fourteen or fifteen I made the decision to venture off to make my life 100% music.
The manager is by himself. He can't mingle with his players. I enjoyed my players, but I could not socialize with them so I spent a lot of time alone in my hotel room. Those four walls kind of close in on you.
Forget about every other lesson in the book. You have to be able to tap your foot or else none of what you doing you are not gonna have any control of your symptom.
But man is a fickle and disreputable creature and perhaps, like a chess-player, is interested in the process of attaining his goal rather than the goal itself.
I played with Joey Mullen back in Salt Lake City before he got called up to St. Louis. He was the first player ever to score 20 goals in the American League and 20 in the NHL. I've kept in contact with him and he's a great guy.
