James Watt

The progress of invention is not a straight line, but a zigzag, and often a very crooked one.

I have been much employed in contriving a method of preventing the waste of steam in the engine, and I think I have succeeded in a great measure, and I hope it will answer my expectations.

The world is not so much in need of new truths as it is of new applications of old truths, and I hope I shall be able to contribute something to that end.

I am not a man of letters, but a man of business, and therefore I must be excused for not writing often, and for not writing well.

The true value of a thing is what it will produce, and not what it will cost, and I hope my engine will produce much.

My head is so full of the engine that I can think of nothing else, and I am almost mad with it, and I hope I shall be able to bring it to perfection.

The greatest good you can do for another is not just to share your riches but to reveal to him his own, and I hope I shall be able to do that for many.

I have a most intense and passionate aversion to the idea of being useless, and I hope I shall never be so, and I hope I shall always be useful.
