The reason why worry kills more people than work is that more people worry than work.

I think work is the world's greatest fun.

I always found that, if I began to worry, the best thing I could do was focus upon doing something useful and then work very hard at it. Soon, I would forget what was troubling me.

Work while others are wishing.

I never did anything by accident, nor did any of my inventions come by accident; they came by work.

I find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.
