Buy goat, sell goat

A Jew comes to Rabbi and starts complaining about his life:
- Rabbi, my life is so hard and I'm so tired. What should I do?
- Buy a goat.
- What? I have a wife and seven kids and we all live in a small apartment and there is no possibility to keep a goat there…
- Just follow my advise.
In a week the Jew comes to Rabbi again and starts complaining about his life even more:
- Rabbi, I followed your advice and now my life is much harder than before: the goat stinks and makes more noise than my wife and seven kids! What should I do?
- Sell the goat.
