How you deal with success is the same as how you deal with non-success. You agitate. You flutter.

All of your lives, you are practicing for success.

Every time things did not go the way you wanted, you called that failure and were disappointed. You were practicing your reaction to success whether you knew it or not. You were moved by your disappointment. Perhaps you cried and retreated. Perhaps you jumped up and down. Perhaps you became stony and couldn't move. Perhaps you were floored.

How you have been handling disappointment is how you will handle success.
