One's final destiny only becomes known after the fact.
This is probably obvious, but we're always looking to tell ourselves something will happen because it's our destiny. If it were that easy, we'd have a society full of actors. "It's my destiny to win an Oscar!" How many misguided souls think it's their destiny to be the next American Idol? Now imagine if it were true. "American Idol winner William Hung/Sanjaya Malakar/anyone from Season 9." And, of course, it's my destiny to win a huge lotto jackpot and never have to worry about money again. (Still waiting on that last one, keepers of the karma...)
In sports, we tend to proclaim destiny at the drop of a hat, but especially when our team hasn't won in a long time and something amazing happens that we take as a sign, an indicator, a guarantee of future success.
