One of my favorite inventors, and one of the most brilinat minds that ever walked the Earth is Nikola Tesla. Here are some Teslas quotes that I especially like:
* I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success... such emotions make a man forget food, sleep, friends, love, everything.
* The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane.
* My method is different. I do not rush into actual work. When I get a new idea, I start at once building it up in my imagination, and make improvements and operate the device in my mind. When I have gone so far as to embody everything in my invention, every possible improvement I can think of, and when I see no fault anywhere, I put into concrete form the final product of my brain.
* Let the future tell the truth, and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I have really worked, is mine.
