I really shouldn't say suffer, because it can lead to greatness, which it has for Bono, but do you think it's a reason for his success?
In the fields of psychology and psychoanalysis, Napoleon complex (or Napoleon syndrome) is a colloquial term used to describe a type of inferiority complex suffered by people who are short. The term is also used more generally to describe people who are driven by a perceived handicap to overcompensate in other aspects of their lives.
Alfred Adler pioneered the psychological work on inferiority complexes, and used Napoléon Bonaparte as an example of someone whom he thought was driven to extremes by a psychological need to compensate for what he saw as a handicap: his small stature.
