Because sometimes that freaks yourself out. You start with Thoughts: Am I playing this right? Should I even play this? WhatifImakeamistakeANDTHEWHOLEWORLDKNOWS? It can get a little unhinged. Dial it back. Instead, say, "Let me show you something" or "Listen to what I learned" or "Isn't this cool/sick/groovy"? Say it like you're amazed. Because it is amazing. To be able to play even a little bit of something someone else recognizes, or of something you created-yes, that is amazing. So show us what you've learned. Show us something cool. And feel the change within you. That's what it's all about.
