The value of a good idea is in using it.

I have far more respect for the person with a single idea who gets there than for the person with a thousand ideas who does nothing.

The first requisite for success is to develop the ability to focus and apply your mental and physical energies to the problem at hand - without growing weary. Because such thinking is often difficult, there seems to be no limit to which some people will go to avoid the effort and labor that is associated with it.

The reason a lot of people do not recognize opportunity is because it usually goes around wearing overalls looking like hard work.

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. I am a sort of a middleman between the long-haired and impractical inventor and the hard-headed business man who measures all things in terms of dollars and cents. My principal business is giving commercial value to the brilliant but misdirected ideas of others.

I was at the foot of my class.

Direct thought is not an attribute of feminity. In this, women are now centuries behind man.
