There is no substitute for 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.
Every wrong attempt discarded is another step forward
Nearly every man who develops an idea works it up to the point where it looks impossible, and then he gets discouraged. That's not the place to become discouraged.
I never failed once. It just happened to be a 2000-step process.
