Thanks to Guy Kawasaki, I just discovered this site called “Letters of Note.” It’s a collection of “correspondence deserving of a wider audience.”
The following quote is from Thomas Edison who is writing a letter of congratulations to a former colleague. What caught my eye was this passage: “The worst is to come, for it takes about seven years to convert the average man to the acceptance of a solved problem.”
Was Edison being sarcastic, pessimistic, optimistic, or realistic?
