In closing, if you do not, now and then, doubt accepted rules, it is unlikely you will be a leader into new areas; if you doubt too much you will be paralyzed and will do nothing. When to doubt, when to examine the basics, when to think for yourself, and when to go on and accept things as they are is a matter of style, and I can give no simple formula on how to decide. You must learn from your own study of life.
