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.

Thomas Alva Edison

My success is due more to my ability to work continuously on one thing without stopping than to any other single quality.

The first requisite for success is to develop the ability to focus.

As a cure for worrying, work is better than whisky.

The secret of success is focus of purpose.

You cannot dwell on the past. You have to focus on the future.

Focus and simplicity...once you get there, you can move mountains.
