There's nothing wrong with athletes, or anyone else for that matter, celebrating their achievements. Just remember that an overzealous celebration can turn your moment of glory into a lifetime of regret unless you know the following:
1. It ain't over till it's over: I know you're excited, but have you already crossed the finish line? That three-point shot that gave you the lead was amazing, but did you actually hear a buzzer? Do not get ahead of yourself.
2. Your limits: Were you able to a backflip from a standing position this morning? If the answer is no, there's not much chance the touchdown you just scored will change that.
3. The value of a proportional response: I know you just laid out the quarterback, but examine your surroundings. Is this a vital play in an important game with potential to influence the outcome or is this a garbage play late in a game that your team is down three or more scores? Those should be two very different celebrations.
4. What goes around comes around: You can have fun, but be respectful. If you celebrate success by enthusiastically disrespecting people, then people will celebrate your failures by enthusiastically disrespecting you.
