I think work is the world's greatest fun.

The injurious agent in cigarettes comes principally from the burning paper wrapper. The substance thereby formed is called "acrolein." It has a violent action on the nerve centers, producing degeneration of the cells of the brain, which is quite rapid among boys. Unlike most narcotics, this degeneration is permanent and uncontrollable. I employ no person who smokes cigarettes.

I never knew I had an inventive talent until Phrenology told me so. I was a stranger to myself until then!

Failure is really a matter of conceit. People don't work hard because, in their conceit, they imagine they'll succeed without ever making an effort. Most people believe that they'll wake up some day and find themselves rich. Actually, they've got it half right, because eventually they do wake up.

When there's no experimenting there's no progress. Stop experimenting and you go backward. If anything goes wrong, experiment until you get to the very bottom of the trouble.

Our greatest weakness lies in giving up.

Let the public throw bouquets to the inventors and in time we will all be happy.
