Success means we go to sleep at night knowing that our talents and ablities were used in a way that served others.

What one has to do usually can be done.

The production of too many useful things results in too many useless people.

I don't want to achieve immortality through my work... I want to achieve it through not dying.

Personally, I enjoy working about 18 hours a day. Besides the short catnaps I take each day, I average about four to five hours of sleep per night.

You must take personal responsibility. You cannot change the circumstances, the seasons, or the wind, but you can change yourself. That is something you have charge of.

You can't just ask customers what they want and then try to give that to them. By the time you get it built, they'll want something new.

Nothing is particularly hard if you divide it into small jobs

By failing to prepare, you are preparing to fail.

Every individual has his own style, his own way of presenting himself on and off the field.
