Thomas Edison

I have always been a great believer in the power of observation.

I have always been a great believer in the power of learning.

I have always been a great believer in the power of knowledge.

I don't think there's any substitute for hard work, and I think that's true of anything that you do.

The mind is the master over the body.

The first thing is to find out what the world needs; then to proceed to invent it.

I have more respect for the fellow who can make a good job of a bad job than for the fellow who can make a bad job of a good job.

I have always been a man of few words, and I have always been a man of many deeds.

The only way to do great work is to love what you do.

It is not because things are difficult that we do not dare; it is because we do not dare that they are difficult.

I have not failed 10,000 times. I have successfully found 10,000 ways that will not work.

The world is full of people who have never had a good idea.

I am not afraid of failure. I am afraid of not trying.

The first thing is to find out what the world needs; then proceed to invent it.

I owe my success to the fact that I never had a watch in my life.

I have friends in both camps. I am a spiritualist, but I am not a spiritualist in the sense that I believe in the phenomena of the séance room. I believe in the existence of a spiritual world, and I believe in the possibility of communication with it.

I believe that the brain is a storage battery of energy, and that it is capable of being charged and discharged. I believe that the brain is a machine, and that it is capable of being improved.

I believe that the greatest discovery that a man can make is to discover himself. To discover his own powers, his own limitations, his own possibilities.

I believe that the human race is just beginning to develop its powers. We are still in the kindergarten stage of our development.

I believe that the purpose of life is to grow, to learn, to expand, to develop. And to help others to do the same.
