Don't let people take advantage of you or twist your words against you. Don't be jealous of other instead appreciate them and learn from their good qualities. Jealousy is a disease a serious one that can make you depressed.....
Can I give you a piece of advice?
Have you ever seen a movie or read a book or even listened to a song where making someone jealous worked in anyone's favour? My advice...don't jump to jealousy, it never goes the way you want it to.
