Human are complicated and yet simple. Simple, becasue no matter how complicated the behavior or emotions of human are, it all comes down to some basic needs; needs that make us animal and needs that make us human. The human behavior or emotions are just interplay and internal/external balances of these needs.
Never underestimate the power of time and the power of buried/underlying emotions. Time is a powerful force that transforms people’s preferences, reshapes their values, and alters their personalities. The emotions are the underlying driving forces for dailly choices, which eventually shape who we are.
