Some other things sports teach us:

The other team does not want you to win; the other team wants you to lose. 

If you throw the ball at your own basket as often as you throw it at your opponent's basket, you're not going to be playing for long. 

Not everybody is good enough to earn a multi-million-dollar salary in the big leagues. Most of us will have to be satisfied with less. Sitting around feeling aggrieved because you can't have everything other people have won't accomplish anything for anybody.
