I didn't grown up sheltered to put it mildly, but I guess you could cite me as an example that you can overcome adversity with willpower. My father tried to commit suicide when I was 5, I ran away from home when I was 9, and became a pro boxer at the age of 16. I'm a true road warrior, as I won the super featherweight title against a Puerto Rican in Puerto Rico, the lightweight title against an Scotsman in England, and I competed for the light welterweight title against an American in the US... Overall I competed as a pro in 4 different decades. Floyd Mayweather Jr. referred to me as his dream opponent in a fantasy match.
