Zeal without knowledge is a runaway horse.
Youth is wasted on the young
You've asked for trouble.
You won't carry a firebrand under your coat very far.
You would do better to sit on a powder keg than on the knee of a woman.
Your body belongs to the Tsar, your soul to God, and your back to the squire.
Your dog wishes you a long life.
Your feet are crooked, your hair is good for nothing, said the pig to the horse.
Your plan doesn't hold water.
You never know what you can do till you try.
You never miss the water till the well runs dry.
You reap what you sow.
You scratch my back, I?ll scratch yours. One hand washes the other.
You will accomplish more if you do things methodically.
You may call me even a pot, just don't put me into the oven.
You might be my friend, but it doesn't entitle you to using my assets (or not repaying my debts).
You must chop down the tree that gives too much or too little shade.
You must keep your word, even if doing so costs you money.
You need sharp axes for knotty trees.
You do not really understand something unless you can explain it to your grandmother.
You don't get a headache from what other people have drunk.
You don't get something for nothing.
You don't learn anything from buying, but you do from selling.
You don't milk a cow with your hands in your pockets.
You get used to everything -- even hell.
