First, you never get to be as good as you want to be at anything. Second, you keep raising the bar as you get better. Accepting this reality gives you growth without your becoming neurotic. You will always be a hypocrite in your performance compared to your stated standards. As with goals, you want some standards out of your reach to make you grow and strive for improvement.
Some people adjust their standards to match their performance.
That's easy but they are stuck at a lower level than they could reach. True, they talk about improvement but they take little, if any, action. They get to really enjoy pleasurable activities such as TV, booze and drugs. A little positive action on your part makes you stand out from the crowd. The world did change on January 1, 2000.
