Self-esteem is as necessary to the spirit as food is to the body. The cure for self-centeredness, self-concern, egotism, and all the ills that go with it, is the development of a healthy, strong ego by building up self-esteem. When a person has adequate self-esteem, little slights offer no threat at all—they are simply “passed over” and ignored. Even deeper emotional wounds are likely to heal faster and cleaner, with no festering sores to poison life and spoil happiness.
