The difference between genius and stupidity is that genius has its limits.

Genius lies in your ability to find solutions to problems you never thought you'd face, in a way that nobody ever thought you'd take.

Genius may have its limitations, but stupidity is not thus handicapped

Genius and stupidity never stray from their respective paths; talent wanders to and fro, following every light.

There's a thin line between genius and bottom-barrel stupidness. I hover delicately on a tightrope between the two, wondering where I'll land if I'll ever fall.

When a great genius appears in the world you may know him by this sign; that the dunces are all in confederacy against him."
