It is easy to see the faults of others, but difficult to see one's own faults. One shows the faults of others like chaff winnowed in the wind, but one conceals one's own faults as a cunning gambler conceals his dice.

Buddha

It takes two flints to make a fire.

Louisa May Alcott

Of all your troubles, great and small, the greatest are the ones that don't happen at all.

Thomas Carlyle

Hard work never killed a man.

Scottish proverb

When you try to stay on the surface of the water, you sink; but when you try to sink, you float.

Zen Proverb

Doing nothing is better than being busy doing nothing.

Lao Tzu
