How Do I Stop Comparing Myself To People, Overcome Jealousy And Be Happy With Who I Am?

Start comparing yourself to you.
The most successful people in life tend to compare themselves to themselves. Like the Williams sisters (Serena and Venus). They never focus on the competition, they focus on what they have put in practice today that they didn’t yesterday.
So the best thing you can do is self improve. What did you do yesterday that you don’t want to do tomorrow? What did you do yesterday that was good so that you can implement it today?
Also, consider getting a hobby that takes up the time when you compare yourself with others. A person who loves themself will improve themself and then use that skill for the betterment of society. i.e. volunteer.
Good Luck.

Our perceptions of other people are based on what we see in them, outwardly. None of us know exactly what it is like to be someone else. Your popular friend may have some inwards feelings of insecurity and she may look at you, outwardly, and think, “I wish I could be as calm as she is.” In other words, most of us wouldn’t actually trade lives with another person, given the chance, if we knew exactly how that other person’s life really was.
I hope this helps.

There are several things you can do to overcome this and be comfortable in your own skin. Make a list of all the good things about yourself such as achievements, personality traits, things that make you unique, ect. You also need to surround yourself with people who make you feel good and are not depressed all the time. Also, eating better and exercising will help boost your mood and you’ll appear happier and more confident without changing who you are.

two exercises, of a psychological nature you might try are
1. Try to REMEMBER YOURSELF. That is, to intentionally be aware of yourself IN THE MOMENT. No matter what you are doing. Washing dishes, walking from one room to the other, WATCH yourself doing this. This will expand out to where you can actually observe your emotions and categorize which emotions are useless.
2. Don’t express negative emotions. You might be HAVING some negative emotions but try your best to not express them. Not in words, in facial expressions, in body language. Imagine how a person who was in a higher state of consciousness might behave. Then BEHAVE that way. By being CONSCIOUS of yourself, without expressing negative emotions.

The beauty of a woman is not in the clothes she wears,the figure she carries or the way she combs her hair,the beauty of a woman must be seen from her eyes,because that is the doorway to her heart,the place where love resides.
