Always look to the future man. Living in the here-and-now can be good...but sometimes it can hurt you later on.
I'll just take what I do and use it as an example, tennis. Say I train really hard to adapt to the kids in 14 & under. They don't hit that hard, I learn to beat them all, so my game is now based around the strength of the other player. Then I move up into the 16 & under (they crush the ball) and I can't use my previous game plan because they hit too hard. Now I start falling down, down, down to the bottom of the ranking system. What good is it to get amazing at beating kids in the 14's, when you have no chance with Pro's?
Sry if that didn't make since, but I know that you like tennis and all Wiired...so I thought i'd give it a shot.
