Learning must be like a house with its door always wide open; let everything enters the house!
Help your brother; and as regards helping, everyone is your brother!
Courage refuses frontiers!
If you have a fish intelligence, you will be easily trapped in the net.
Not every thought is a flower; some are thorns. But while a flower may make you fall asleep and too see dreams, a thorn will wake you up and make you to think!
Some boats are rotten in the ports; some boats shine in the hard journeys!
