If you are a hindu , you go through four stages in your life.
1)Childhood.
2) Brahmacharya: Young adult who maintains celibacy before marriage, and concentrates on studies/plans for future.
3) Varnashrama: Married life with wife and kids.
4) Sannyasa: As your youth fades and you go into old age, you plan to find enlightenment by renouncing everything (renouncing them mentally usually now a days).
This is based on the principles of Dharma, Artha, Kama, Moksha.
In order to lead a good life, one needs to follow Dharma (Hindu duties) , Artha : Gain wealth in one's life. Kama: Fulfill his duty as a human being and beget children. Moksha : Gain enlightenment at the end of his life.
Some good hindu principles are:
Ahimsa: Nonviolent attitude toward animals, reverence to life. (some follow vegetarianism for this reason).
Satya: Truthfulness
Asteya: Non stealing/honesty
Brahmacharya: Practicing divine conduct by controlling lust.
Kshama: Patience.
Dhriti: steadfastness.
Daya: compassion toward all beings.
Arjava: honesty in livelihood.
Mitahara: Moderation in enjoyment of food, entertainment etc.
Saucha: Purity of Heart, mind and action.
