The Imprisonment of Fear

If you put fleas in a shallow container, they will rapidly jump out. But if you put a lid on the container for a short time, the fleas will hit the lid, learn to jump only so high, and give up the quest for freedom. After the lid is removed, the fleas will remain imprisoned by their own self-imposed limitations. So it is with life - most people let their own fears, or the impositions of others, imprison them in a world of low expectations.
