Thomas Edison on genius

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

There is no substitute for hard work.

Many of life’s failures are people who did not realize how close they were to success when they gave up.

Not great understanding alone, not intelligence alone, nor both together, make genius. Love! Love! Love! that is the soul of genius.

Genius without education is like silver in the mine.

Benjamin Franklin1706–1790Poor Richard’s Almanack

• Education

No great genius has ever existed without some touch of madness.

Aristotle384–322 BC
