Become interested in things outside of yourself.

Do not brood over what is said to you, or analyze every simple remark until you magnify it into something of the greatest importance.

Do not have such a low and unjust estimate of people as to think they are bent on nothing but hurting the feelings of others, and depreciating and making light of them on every possible occasion.

A man who appreciates himself at his true value, and who gives his neighbors credit for being at least as good as he is, cannot be a victim of over-sensitiveness.
One of the best schools for a sensitive boy is a large business house in which he will be thrown among strangers who will not handle him with gloves.

In such an environment he will soon learn that everyone has all he can do to attend to his own business.
