To keep your balance, you must keep moving. Try not to become a man of success, but rather try to become a man of value. The true sign of intelligence is not knowledge but imagination. Education is what remains after one has forgotten what one has learned in school.
Whoever is careless with the truth in small matters cannot be trusted with important matters. We cannot solve our problems with the same thinking we used when we created them. The only source of knowledge is experience. The difference between stupidity and genius is that genius has its limits. Joy in looking and comprehending is nature’s most beautiful gift.
