Above all, to thine own self be true.
When in Rome, do as the Romans do.

It's never too late to learn.
You can't teach an old dog new tricks.

Good things come in small packages.
The bigger, the better.

If at first you don't succeed, try, try again.
There's no point in beating a dead horse.

He who hesitates is lost.
Act in haste, repent at leisure.

Two's company, Three's a crowd.
The more, the merrier.

Do it well, or not at all.
Half a loaf is better than none.

Nothing ventured, nothing gained.
Better safe than sorry.

Never judge a book by its cover.
Clothes make the man.

Out of sight, out of mind.
Absence makes the heart grow fonder.

Many hands make light work.
Too many cooks spoil the broth.

Actions speak louder than words.
The pen is mightier than the sword.

Never change horses in the middle of a stream.
Variety is the spice of life.

Practice makes perfect.
All work and no play makes Jack a dull boy.

A penny saved is a penny earned.
The love of money is the root of all evil.
