You have to go on and be crazy. Craziness is like heaven.

Love is a sort of insanity.

If some people are so hungry for a feeling of importance that they actually go insane to get it, imagine what miracle you and I can achieve by giving people honest appreciation this side of insanity.

I had to admit, standing there, that sometimes you just gotta admire the passion of the truly insane — a passion that bulls right past all sense or reason.

Make sure everything you do is so completely crazy it’s unbelievable.

By this time I was in a state of excitement bordering on insanity; but I also had the cunning of the insane.

Yet egotism can also be useful to ambitious creatures, driving their single-minded pursuit of success. Madness seems essential in order to be “great.

Achieving the impossible requires that you outwit your voice of reason and access the whimsical part of your nature that inherently delights in the possibilities of the imagination.

Some might think that the creativity, imagination, and flights of fancy that give my life meaning are insanity.

In order to attain the impossible, one must attempt the absurd.

Insanity is catching.

There is a fine line between insanity and genius.

One man's insanity is another man's genius; someday the world will recognize the genius in my insanity.

Some idiotic things are well worth doing.
