I am a vegetarian as well as a passionate anti-alcoholic, because I can thus make better use of my brain.

A teacher sent the following note home with a six-year-old boy 'He is too stupid to learn.' That boy was Thomas A. Edison.

I think that Ingersoll had all the attributes of a perfect man, and, in my opinion, no finer personality ever existed. Judging from the past, I cannot help thinking that the intention of the Supreme Intelligence that rules the world is to ultimately make such a type of man universal.

A reporter called on Edison to interview him about a substitute for lead in the manufacture of storage batteries that the scientist was seeking. Edison informed the man that he had made 20,000 experiments but none had worked. "Aren't you discouraged by all this waste of effort?" the reporter asked. Edison: "Waste! There's nothing wasted. I have discovered 20,000 things that won't work."

Waste is worse than loss. The time is coming when every person who lays claim to ability will keep the question of waste before him constantly. The scope of thrift is limitless.

Youth doesn't take advice.

I have not failed. I've just found 10,000 ways that won't work.
