Chanakya Neethi Part 2/17..

1. Untruthfulness, rashness, guile, stupidity, avarice, uncleanliness and
  cruelty are a women's seven natural flaws.
2. To have ability for eating when dishes are ready at hand, to be robust
  and virile in the company of one's religiously wedded wife, and to have
 a mind for making charity when one is prosperous are the fruits of no
ordinary austerities.
3. He whose son is obedient to him, whose wife's conduct is in accordance
  with his wishes, and who is content with his riches, has his heaven here
 on earth.
4. They alone are sons who are devoted to their father. He is a father who
  supports his sons. He is a friend in whom we can confide, and she only
 is a wife in whose company the husband feels contented and peaceful.
5. Avoid him who talks sweetly before you but tries to ruin you behind
  your back, for he is like a pitcher of poison with milk on top.
6. Do not put your trust in a bad companion nor even trust an ordinary
  friend, for if he should get angry with you, he may bring all your secrets
 to light.
7. Do not reveal what you have thought upon doing, but by wise council
  keep it secret being determined to carry it into execution.
8. Foolishness is indeed painful, and verily so is youth, but more painful
  by far than either is being obliged in another person's house.
9. There does not exist a ruby in every mountain, nor a pearl in the head of
  every elephant; neither are the sadhus to be found everywhere, nor
 sandal trees in every forest.
10. Wise men should always bring up their sons in various moral ways, for
children who have knowledge of niti-sastra and are well-behaved
become a glory to their family.
11. Those parents who do not educate their sons are their enemies; for as is
a crane among swans, so are ignorant so are ignorant sons in a public
assembly.
12. Many a bad habit is developed through overindulgence, and many a
good one by chastisement, therefore beat your son as well as your pupil;
never indulge them. ("Spare the rod and spoil the child.")
13. Let not a single day pass without your learning a verse, half a verse, or
a fourth of it, or even one letter of it; nor without attending to charity,
study and other pious activity.
14. Separation from the wife, disgrace from one's own people, an enemy
saved in battle, service to a wicked king, poverty, and a mismanaged
assembly: these six kinds of evils, if afflicting a person, burn him even
without fire.
15. Trees on a river bank, a woman in another man's house, and kings
without counsellors go without doubt to swift destruction.
16. A brahmana's strength is in his learning, a king's strength is in his
army, a vaishya's strength is in his wealth and a shudra's strength is in
his attitude of service.
17. The prostitute has to forsake a man who has no money, the subject a
king that cannot defend him, the birds in a tree that bears no fruit, and
the guests in a house after they have finished their meals.
18. Brahmanas quit their patrons after receiving alms from them, scholars
leave their teachers after receiving education from them, and animals
desert a forest that has been burnt down.
19. He who befriends a man whose conduct is vicious, whose vision
impure, and who is notoriously crooked, is rapidly ruined.
20. Friendship between equals flourishes, service under a king is
respectable, it is good to be business-minded in public dealings, and a
handsome lady is safe in her own home.
