A good quotation is a very strong wind; it can change a man's direction!
A dry well is not a friend of a thirsty man; and an ignorant man, of the progression!
When you do your work happily, work will disappear.
Be silent when you are criticised so that you can hear the critiques well!
On the way to truth, walk with the crowds or walk all alone; but walk always and walk under every condition!
We can't change our fate, because we can't change something which doesn't exist.
