Jealousy is a terrible emotion. It makes you think that you are not in control of your life. It makes you think that other people have stolen something from you that is yours. Rather, something that you think should be yours. But the bad part is the reason you are stuck in the place you are is because of your jealousy. When you start to blame other people for your problems, that is your problem.
Eleanor Roosevelt said “No one can make you feel inferior without your consent.” Likewise, all of your emotions are up to you. Someone else cannot make you feel angry or sad or upset or even happy. You choose to feel these feelings when they say or do whatever they say or do. You are entirely responsible for how you feel, not other people. For you to make your happiness or sadness dependent on someone else is to give away all of your power.
