Some people can jump higher and run faster than others. Some have better minds than others. Some have more musical talent than others. Not everyone will win. We will not receive equal prizes.
Joy comes from doing the very best we can with the gifts we possess. Doing our very best is good enough. A 3.5 tennis player can have just as much fun as a 7.0 player as long as that 3.5 player gives best effort.
For the right minded, effort trumps result. We can expect the opportunity to give our best effort, but we cannot expect that our best effort will produce results better than the efforts of others. Doing our best is the best we can expect of ourselves.
