Genius is not inspired. Inspiration is perspiration.
Remember, life is all what you focus on. Learn lessons and keep moving forward towards your goals and dreams... "I have not failed. I've just found 10,000 ways that won't work."
The secret of success is focus of purpose.
I start where the last man left off.
I am quite correctly described as 'more of a sponge than an inventor....'
X-rays ... I am afraid of them. I stopped experimenting with them two years ago, when I came near to losing my eyesight and Dally, my assistant practically lost the use of both of his arms.
