Have you noticed?
Some people will just not be stopped. They have accomplished much despite adversity. They refuse to listen to their fears. Nothing anyone says or does holds them back.
As Ted Engstrom insightfully writes in his book Pursuit of Excellence:
"Cripple him, and you have a Sir Walter Scott.
Lock him in a prison cell, and you have a John Bunyan.
Bury him in the snows of Valley Forge, and you have a George Washington.
Raise him in abject poverty and you have an Abraham Lincoln.
Strike him down with infantile paralysis, and he becomes Franklin Roosevelt.
Burn him so severely that the doctors say he'll never walk again, and you have a Glenn Cunningham -- who set the world's one-mile record in 1934.
Deafen him and you have a Ludwig Von Beethoven.
Have him born black in a society filled with racial discrimination, and you have a Booker T. Washington, or George Washington Carver.
Call him a slow learner, "retarded," and write him off as ineducable, and you have an Albert Einstein."
