We all have heard the phrase “do or die.” How do you think it came about? It sounds like somebody was facing a dilemma: If I do not do this deed, I will die. The death can be physical, or metaphorical. Losing a game, or failing an exam, qualifies as a deadly experience. Have you been in this situation? Most of us have. Do you remember what helped you cheat death or defeat? Most likely, it was your belief that you could do the deed.
