Why do I always envy other people's lives, and every time I brush WeChat friends circle, I feel how good other people's lives are?

Because everyone is concerned about what you lack in life, such as money, beautiful women, luxury houses, luxury cars and so on. In fact, people who have the above wealth or resources also envy you. Such as your health, your youth, your vitality, and so on. It is your ability to think about how to change your existing resources into what you want.
