Little strokes fell great oaks.
Live and let live.
Mind your p's and q's.
Money is the root of all evil.
Never put off to tomorrow what you can do today.
Once bitten, twice shy.
One picture is worth a thousand words.
One rotten apple spoils the whole barrel.
Rome wasn't built in a day.
Silence is golden.
Spread the table and contention will cease.
The best laid plans of mice and men often go awry.
The bigger they are the harder they fall.
The devil dances in empty pockets.
The grass is always greener on the other side.
The leopard cannot change its spots.
The proof of the pudding is in the eating.
There's more than one way to skin a cat.
Two wrongs don't make a right.
What will be, will be.
When in Rome, do as the Romans do.
