Focusing is about saying No.

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

The secret of success is focus of purpose.

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

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

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.
