“Life is a long lesson in humility”

“All things are difficult before they are easy ”

“Study until twenty five, investigate until forty, profession until sixty, at which age I would have him retired on a double allowance”

“It’s none of their business that you have to learn how to write. Let them think you were born that way”

“A teacher affects eternity; he can never tell, where his influence stops”

“They know enough who know how to learn”
