Once upon a time, there was a man he was terribly unhappy. Someone told him that he should go and see this wise man outside the village for advice. So he went.
The wise man asked him what his problems were. He made a long list about the problems at home with the wife and the children.
When he finished, the wise man asked him to buy a goat and take it home. He didn't understand why but did it anyway.
A week later, he went to see the wise man again and told him it did not work, the bloody goat was making his life Hell and how it made a mess in the house and in the garden. He had to spend day and night taking care of it.
The wise man sent him away. A month later, the man returned and said he couldn't take it anymore, it'd gotten from bad to worse.
The wise man then tell him, "Sell the goat now and go home". The man sold the goat and went home. He could not believe how wonderful it felt. He's forgotten all about his previous problems !!
