If today were the last day of my life, Would I want to do what I'm about to do today? And whenever the answer has been "no" for too many days in a row, I know I need to change something.

Cutting negative people from my life does not mean I hate them, it simply means I respect me.

Heaven, as conventionally conceived, is a place so inane, so dull, so useless, so miserable that nobody has ever ventured to describe a whole day in heaven, though plenty of people have described a day at the seaside.

I am not discouraged, because every wrong attempt discarded is another step forward.

I owe my success to the fact that I never had a clock in my workroom.

I never failed once. It just happened to be a 2000-step process.
