Initiated ISKCON devotees make life-long vows to abstain from eating meat, gambling, intoxication and illicit sex. In addition they chant 16 'rounds' of the Hare Krishna maha mantra every day. One doesn't have to live as a renunciate, rather, one can get married and take responsibilities for one's family and society as a whole. This is the formula for happiness.
