A bird in the hand is worth two in the bush.
A bad workman blames his tools.
Don't put all your eggs in one basket.
Practice makes perfect.
Love all, trust a few, do wrong to none. (W. Shakespeare)
Truth is stranger than fiction; fiction has to make sense.
Time is a great healer.
Haste makes waste.
Beauty is only skin deep.
History repeats itself.
Don't make a mountain out of a molehill.
Constant dropping wears away a stone.
Let sleeping dogs lie.
A drowning man will clutch at a straw.
Men occasionally stumble over the truth, but most of them pick themselves up and hurry off as if nothing ever happened.
Bad news travels fast.
The end justifies the means.
Clothes do not make the man.
Don't look a gift horse in the mouth.
An ounce of prevention is worth a pound of cur.
