Assume on an $8 \times 8$ chessboard with the usual coloring. You may repaint all squares:
(a) of a row or colum.
(b) of a $2\times 2$ square
The goal is to attain just one black square. Can you reach the goal?

I think we judge talent wrong. What do we see as talent? I think I have made the same mistake myself. We judge talent by the trophies on their showcases, the flamboyance the supremacy. We don't see things like determination, courage, discipline, temperament.

Re: Coloring chessboard
The number of black cells $mod 2$ stays invarient. Whih is at the start an even number. So, the desired state is impossible to reach.
Frankly, my dear, I don't give a damn.
