Fear

Cowards die many times before their deaths; The valiant never taste of death but once. Of all the wonders that I yet have heard, It seems to me most strange that men should fear, Seeing that death, a necessary end, Will come when it will come.

— William Shakespeare, "Julius Caeser", II.ii

Fear limits our agency. It keeps us from doing what we want to do, either directly or by preventing a precondition from occurring. Taking our agency into our own hands involves understanding our fear and determining how we want it to impact our actions.
