Give an infant a blank canvas and paints and watch him instantaneously dress the white square with sloppy lines of reds, blues and yellows.
Crossing each other in no logical sequence.
Mixing into awful shades of greens and browns.
But observe his face as he does so.
And you will see his face flushed with joy,
With every rush of the brush.
With no designated design in mind.
He loves to paint.

Give an adult a blank canvas and paints.
And the first thing he'll ask you is;
"What do you want me to paint?"
