If you are a hindu , you go through four stages in your life.
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.
