Feeling of inferiority comes about for just one reason: We judge ourselves, and measure ourselves, not against our own "norm" but against some other individual's "norm." When we do this, we always, without exception, come out second best. But because we we think and believe and assume that we should measure up to some other person's normal, we feel miserable, and second rate and conclude that there is something wrong with us.
The Next logical conclusion in this cockeyed reasoning process is to conclude that we are not "worthy", that we do not deserve success and happiness, and that it would be out of place for us to fully express our own abilities and talents, whatever they might be, without apology, or without feeling guilty about it.
All of this comes about because we have allowed ourselves to be hypnotized by the entirely erroneous idea that "I should be like so-and-so" or "I should be like everyone else."
Let me tell you, "Everyone else" is composed of individuals, no two of whom are alike.
Inferiority and superiority are reverse sides of the same coin. The cure lies in realizing that the coin itself is adjective.
The truth about it, is this:
YOU are not "inferior"
YOU are not "superior"
YOU my friend are simply "YOU"
YOU as a personality are not in competition with any other personality simply because there is not another person on the face of the earth like you, or in your particular class.
YOU ARE AN INDIVIDUAL.
Stop measuring yourself against other peoples standards, you are not them, and can never measure up. Neither can they measure up to yours, nor should they. Once you see this simple, rather self-evident truth, accept it, and believe it, your inferior feelings will vanish.
