You will never know exactly what another person is going through or what their whole story is. When you believe you do, realize that your assumptions about their life are in direct relation to your limited perspective. Many people you believe to be successful are extremely unhappy. Many people you think have it easy worked their tail off achieve what they have. Many people who appear to be wealthy are in debt because of their extravagant tastes for material possessions. Many people who appear to you to be old and uncool were once every bit as young and hip and inexperienced as you. When people start to belittle you or judge you, keep your head up and walk away. Never get low to their level, just know that you are better.
