There will always be something we don’t like about ourselves especially if we start comparing ourselves to others. In my opinion, that never solves anything because we will never be that other person.
If you are 5’4 and envy someone who is 6’ you can’t change your height but you can certainly change the message that you give to yourself about your height. Make it a positive thing.
We need to love ourselves and our qualities. There will always be someone who envies something about you.
