The four pillars of a happy life are faith, family, friendship, and work. Faith is about finding a sense of peace through a philosophy or life that's bigger and puts one's life in perspective. Family represents an intense, mystical love, and it's advised to maintain family relationships unless there's abuse. Friendship is distinguished between real friends and deal friends, emphasizing the value of real, beautifully useless friends. Lastly, happiness at work is not about materialistic gains, but about earning success and serving others by creating value in one's life for others.
