"Oh look at what advanced spells that witch can do!" says your friend. "Oh my God, do you see what that wizard is doing!?!?" says another person from the crowd. Yes, you coldly think, I do see for a fact! I am not blind! But then you think that those people are correct! This witch/wizard IS so much better than the common! Heat rises in your body. Envy Ivy climbs up your body and curls in your brain. YOU should be that witch/wizard showing the common up onstage! That's it, you are angry and jealous. But you shouldn't be!

Think about your own personal abilities, and bet that that person onstage will badly lose to you when you perform that ability against that person onstage! You will be the talk of the town! And if that doesn't help, just put that person past you. If you really want to be as great as the person you are watching, study as hard as possible and work very, very hard too. 

Just forget about that person onstage. You are you, the awesome witch/wizard who has a talent for (your talent here)! If you put these show-offs out of your thoughts and concentrate on you and your work, you will be, for sure, the most talented person who will ever live! So don't be green with envy. That makes you a bad person. Cut that Envy Ivy down and move on up!
