Forbidden fruit is sweetest.

Nothing venture, nothing gain.

It is no use crying over spilt milk.

Every cloud has a silver lining.

Prevention is better than cure.

Practice makes perfect.

To be or not to be! That is the question! (W. Shakespeare)

Actions speak louder than words.

All roads lead to Rome.

Don't make a mountain out of a molehill.

Love all, trust a few, do wrong to none. (W. Shakespeare)

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former. (A. Einstein)

Bad news travels fast.

Too many cooks spoil the broth.

All that glitters is not gold.

Beauty is only skin deep.

A room without books is a body without soul.

It is a double pleasure to deceive the deceiver.

A friend in need is a friend indeed.

Fortune is fickle.
