Through this over the decades. BYU and the Jazz will usually let you down, that's a given. You'll eventually get to the point where you're not as invested emotionally, as you age. Then your tolerance level reaches a nice even point.
Then you just enjoy the sports for what they are. Teenagers and young 20 yr olds just tossing around a ball. I still enjoy sports but realize only a small handful of teams actually win consistently....the other 95% of teams all lose. It's all good. Glad we have sports for a little entertainment in mortality.
