That is the trouble with many inventors; they lack patience. They lack the willingness to work a thing out slowly and clearly and sharply in their mind, so that they can actually "feel it work." They want to try their first idea right off; and the result is they use up lots of money and lots of good material, only to find eventually that they are working in the wrong direction. We all make mistakes, and it is better to make them before we begin.

The future will show whether my foresight is as accurate now as it has proved heretofore.

There is no energy in matter other than that received from the environment

My belief is firm in a law of compensation. The true rewards are ever in proportion to the labour and sacrifices made.

Each day we go to our work in the hope of discovering.

Every effort under compulsion demands a sacrifice of energy. I never paid such a price.

It seems that I have always been ahead of my time. I had to wait nineteen years before Niagara was harnessed by my system, fifteen years before the basic inventions for wireless which I gave to the world in 1893 were applied universally.
