Interest is the invention of Satan.

There is a better way to do it - Find it!

Radio is just a fashion contrivance that will soon die out. It is obvious that there never will be invented a proper receiver!

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."

I find out what the world needs. Then I go ahead and try to invent it

I never did anything worth doing entirely by accident. . . Almost none of my inventions came about totally by accident. They were achieved by having trained myself to endure and tolerate hard work.

When I have fully decided that a result is worth getting I go ahead of it and make trial after trial until it comes.
