I agree 100%...some realize it sooner than others and some never do. I used to be the guy that got so freaking angry whenever my teams lost a game. Like legit be in a bad mood and not want to talk to anyone for a few days. I had it bad lol. My then girlfriend...25th of this month will make 8 yrs of marriage....but at the time she made me see how stupid I looked for being upset over a game. During one of my rages after a Falcons lost, in the sweetest voice ever she said "It's only a game". I'm a big guy 6'5 350lbs and those 4 simple words rocked me to the core. Since then I don't allow it to affect my personal life. Win or lose it doesn't affect my life one bit lol. If any of the teams I root for win a championship I'll be happy but its not like I'll receive a ring or anything. It wouldn't affect my life in any way. Like you said it's all wasted time. I just turned 35 a few weeks ago and I'm just thankful I was able to realize this in my late 20's.
