Don't go to the woods if afraid of wolves.
If you are afraid of some difficulties that inevitably accompany any venture, you will never achieve anything, this Russian proverb says.
And in fact, if you are afraid of wolves, which may not be found in the nearby forest, you will never pick up berries or mushrooms.
And if you take the risk and start a seemingly difficult venture, it may not be so scary and you can do it.
The closest English equivalent of this proverb is "Nothing ventured, nothing gained".
