Once aI worked with my uncle on a very hot day pouring about 300 feet of sidewalk. Uncle Gary told me not to spend too much time finishing in one area. "We might lose the battle but we have to win the war."
Spending too much time perfecting 3 feet will make 297 feet garbage. It's better to work in phases quickly laying the material and working the whole project into a good product.
With sports it is better to get out there and play the game and learn how to work with your team, your skill and your opponent than to fixate upon the results of one game.
