"I am always doing things I can't do, that's how I get to do them." ~ Pablo Picasso
This thought worms its way into one's confidence and self image - and suddenly the achievement is thrown into doubt. It was all just a fluke - luck - had nothing to do with ME. There is a reason why a fluke is also a parasite. Parasites live off of you, drain your energy, take what they need and leave you with nothing.
So we set out to see if it was just a fluke - can we do it again? - or can we not? And this thought eats at us. And if we don't do it again, does that mean that WE never did what they actually, really, did?
The other interesting tendency I notice is that we rarely call a bad race a 'fluke'. Nooooo. The bad races are entirely MY fault. The bad races show what I'm really made of. But the good races? Nah. That's all just fickle luck. We berate ourselves for our failures and shrug off our successes.
