The third man

There are three men. All are presented with the same problem.

The first man says, I will work as hard as I can, suffer and sweat until I solve this problem, no matter how hard it is.

The second says, This problem is too hard. I'll never be able to solve it.

The third says very little, and just stares in wonder and curiosity at the turmoil of the problem and the other two men, wonders and thinks about their interaction.

I'm the third man.
