Agonizing over decisions and the strive for perfection are like a bicyclist attempting to compete in a NASCAR race. You must be nimble in your decision making, decisive in your choices, swift in your actions, and persistent as you follow through to completion. Anything less ensures that your more agile competitors will always have the upper hand, leaving you choking on their exhaust.
For those thinking that you have to get everything “right” or “perfect”, you must remember that those are relative terms that never produce significantly better results. Simply make the best choice in the moment and move on with speed. Any extra effort towards perfection will gain you nothing more than a view from the stands as the competition takes home the prize of the business you were after.
