I think it definitely helps to be really focused on what you are doing. You can only work so many hours, and I try to have some balance in my life and so on. I think a lot of people go through this in school.

To get something new done you have to be stubborn and focused, to the point that others might find unreasonable.

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.

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

A lot of people are focused on taking over the world or doing the biggest thing and getting the most users. I think part of making a difference and doing something cool is focusing intensely.

The less I say the more my work gets done.
