A bird does not sing because it has an answer. It sings because it has a song.
The palest ink is better than the best memory.
Be not afraid of growing slowly, be afraid only of standing still.
Do not employ handsome servants.
Do not remove a fly from your friend's forehead with a hatchet.
Keep your broken arm inside your sleeve.
Raise your sail one foot and you get ten feet of wind.
The gem cannot be polished without friction, nor man perfected without trials.
To know the road ahead, ask those coming back.
When you drink the water, remember the spring.
