Actions speak louder than words.
The pen is mightier than the sword.
Look before you leap.
He who hesitates is lost.
A silent man is a wise one.
A man without words is a man without thoughts.
Clothes make the man.
Don't judge a book by its cover.
Many hands make light work.
Too many cooks spoil the broth.
Nothing ventured, nothing gained.
Better safe than sorry!
It's the squeaky wheel that gets the grease.
The nail that sticks out gets hammered.
