“We are all geniuses up to the age of ten.”

“For what is genius, I ask you, but the capacity to be obsessed? ...We have all been geniuses, you and I; but sooner or later it is beaten out of us, the glory faded, and by the age of seven most of us are nothing but wretched little adults.”

“You have two numbers in your age when you are ten. It's the beginning of growing up.”

“In the field, one quickly learns that everything that was funny at age ten is funny all over again.”

“All the labor of all the ages, all the devotion, all the inspiration, all the noonday brightness of human genius are destined to extinction. So now, my friends, if that is true, and it is true, what is the point?”

“A man's genius seems to befriend the more when he reads with open heart, the masterpiece of masterminds, the sagacity of sages, and the ingenious words of geniuses of ages.”
