"Dont sacrifice what you what most for what you want now. write down what you want most and see it often."

     What peter vidmar is trying to say is what you want and what you need are two completely different things and whether you strive for either one of them is a sign of willpower. Do not let temptation cloud the judgment of the choices you make in life, for example maybe your mom gives you money to buy groceries but you are tempted to use the money for that game you've always wanted, you know buying the groceries is want you need but your judgment was thrown off by what you want; hence the game. if you strive for what you need the most everything else seems irrelevant.

persuasion, persistence, and self knowledge of priorities beat temptation and clouded judgment.
