Modesty will save You!

Here is an easy way to distinguish a self centered prick from modest magic guy.

Modesty is a trait that is essential if you don't wanna come across an ego driven dick. I've said this before. So if you figured out a nice count with cards and you call it a Ghost Count, that is modest. Even if everybody else calls it an Elmsley Count later on. This is a nod towards the creator, giving credit where credit is due.
But if you created a control with cards and you call it "The Lorayne Control" you seem smug to the rest of the magic people.

I wonder what "The HaLo Cut" stands for!

So check your magic friends repertoire. If they name any effect/method/prop after themselves, you should be careful.
