How many times has Limbaugh been fired in his life?
He could have wound up unemployed, homeless, a wino, but no, whatever bad happened to him he simply went on, took risks, devloped a plan, stuck with it.

EGO.
It isn't necessarily unhealthy at all, unless it starts getting in the way of enjoying life.
