It's natural to compare yourself to others. We all do it, in pretty much every part of our lives. Jealousy is also normal. However, we shouldn't base our happiness on other peoples successes. And we shouldnt "act" on jelousy, there's no need. If you feel bitter you need to work on changing your mindset and changing things you are unhappy about. OR unfollow/block whatever upsets you.
How many times...
