Seconding Taylor and nothing goes better with it than a huge party with lots of drinks and friends and so on, you know the deal.
Schadenfreude.
I think the feeling of having run a personal best time has to make this list somewhere. It feels physically terrible, but spiritually amazing.
Natürlich.Schadenfreude ist die beste Freude
Winning a national championship. Later having people ask you what your ring is from.
It's definitely when the crowd cheers for you.
