Drips of water penetrate rocks, and ropes cut wood. A young man who doesn’t work hard will become a sad old man

If you don’t accumulate small steps, you can’t reach a thousand miles; if you don’t accumulate small streams, you can’t become a river. A horse can't take ten steps with one leap; a horse can ride ten times without giving up its merits. If you persevere, the rotten wood will not be broken; if you persevere, the metal and stone can be carved. Earthworms have no sharp claws and teeth, nor strong bones and muscles. They eat earth and drink from the underworld. They have only one intention.
