If you put out another's candle, you also will be in the dark.
Nobody is trodden upon unless he lies down first.
He who is grateful for a kindness unlocks the door for another.
Never give advice unasked.
Advising is easier than helping.
When you sweep the stairs, you start at the top.
Never trust to another what you should do yourself.
Don't try to fly before you've grown feathers.
The best penitence; never do it again.
If you don't light fires, smoke won't get in your eyes.
