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.

Education isn't play--and it can't be made to look like play. It is hard, hard work. But it can be made interesting work.

To invent, you need a good imagination and a pile of junk.

Most of my ideas belonged to other people who never bothered to develop them.

Failure is the most effective technique to optimize strategic planning, implementation and processes.

It has been just so in all my inventions. The first step is an intuition-and comes with a burst, then difficulties arise. This thing that gives out and then that-"Bugs"as such little faults and difficulties are called show themselves and months of anxious watching, study and labor are requisite before commercial success-or failure-is certainly reached.

I never failed. It just didn't work 10,000 times.
