Michael Jordan(I)

In a 1988 game against the Utah Jazz, he dunked over John Stockton, who was 6' 1" and 175 pounds. A Jazz fan heckled him, saying, "Why don't you dunk on somebody your own size?" The next trip down the floor, Jordan dunked again, this time on 6' 11", 285-lb. center Melvin Turpin. He then turned to the fan and said, "Was he big enough?".

If you're trying to achieve, there will be roadblocks. I've had them; everybody has had them. But obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it.
