JEALOUSY IS A WASTED EMOTION.

People who love themselves and recognize their worth are unable to be jealous of others. Why?
You should be so preoccupied with loving yourself and changing what you don't like, you have no time to worry about what others are doing.
Being jealous of someone is a waste of energy.
You cannot control other people and the choices they make, or the luck they have.
Weak people let other's circumstances affect their self-love and/or self-worth.
Resist the temptation to be envious, as it will get you nowhere.
If anything, let other people motivate you to achieve certain goals for yourself.
