Man's nature is such that whatever he becomes accustomed to is his pleasure, be it eating, drinking, or any activity.

• If he becomes accustomed to what is bitter, bitterness gives him pleasure;
• if he becomes accustomed to what is sour then sourness gives him pleasure;
• if he becomes accustomed to eat sweets then he will like sweet things.
• Some men get into the habit of complaining about their life, and if they have nothing to complain about then they look for something to complain of.
• Others want the sympathy of their fellow-men and want to explain to them that they are badly treated. It is an intoxication.
• Then there is the person who has fallen into the habit of theft; he derives pleasure from it and the habit becomes stronger and stronger, and when another source of income is offered to him he is not interested, he does not want it.
