Look before you leap.
He who hesitates is lost.
Absence makes the heart grow fonder.
Out of sight, out of mind.
You’re never too old to learn.
You can’t teach an old dog new tricks.
Better safe than sorry.
Nothing ventured, nothing gained.
Don’t look a gift horse in the mouth.
Beware of Greeks bearing gifts.
Do unto others as you would have others do unto you.
Nice guys finish last.
Many hands make light work.
Too many cooks spoil the broth.
The squeaky wheel gets the grease.
Silence is golden.
