How to grasp the emotional life?

People living in this world should take three kinds of feelings seriously: affection, friendship and love.

Family ties are readily available and are often not cherished. Friendship follows one's inclinations, becomes a victim of fame and fortune, and has no confidant. Love is driven by endocrine hormones. I don't know if this is a family relationship for the rest of my life.

We should grasp three emotions: first, learn to make money; second, treat others sincerely; third, have a purpose and plan; fourth, emotions are priceless.
