A failure teaches you that something can't be done-that way.
I've realized that most of my best ideas have followed a good night's sleep.
Genius is not inspired. Inspiration is perspiration.
Smoking too much makes me nervous. Must lasso my natural tendency to acquire such habits. Holding heavy cigar constantly in my mouth has deformed my upper lip, it has a sort of Havana curl.
Whatever the mind of man creates, should be controlled by man's character.
The great trouble is that the preachers get the children from six to seven years of age and then it is almost impossible to do anything with them.
The money one gets for selling one's soul is always spent in deadening one's conscience, so the net gain at the end of a lifetime is no greater than if the diabolic bargain had not been struck.

I am more of a sponge than an inventor. I absorb ideas from every source. I take half-matured schemes for mechanical development and make them practical.

My principal business is giving commercial value to the brilliant but misdirected ideas of others.
