He who speaks without modesty will find it difficult to make... - Confucius

"Give a bowl of rice to a man and you will feed him for a day. Teach him how to grow his own rice and you will save his life."

"It is easy to hate and it is difficult to love. This is how the whole scheme of things works. All good things are difficult to achieve; and bad things are very easy to get."

"he who will not economize will have to agonize"

"Wenn du weißt, behaupte, dass du es weißt. Und wenn du etwas nicht weißt, gib zu, dass du es nicht weißt. Das ist Wissen."

"Choose a job you love, and you will never have to work a day in your life."
