- Cause it's the Easiest way to Steal Your Happiness. And you can always find someone who is taller, prettier, smarter etc. if you look for that...

( but I am sure that You have something They Don't Have - & You can do Something they Can't!  😉 ) 

So instead of focusing on 'how much you think someone is better than you' - focus on your own Passions, Talents & All the Things You're Good At!  ^_^

- & This point of view will make you Feel Much Happier!

( I Assure You About That! 😁👍 )
