Are ya still having fun?

Hey, remember how much fun you had in that very first improv class that you ever took? Now, its years later and you're onstage and your face is all screwed and twisted, brow furrowed, and your whole body shows the strain going on inside your brain. What happened?
Stop being so serious! dont put all that pressure on yourself to be funny clever and witty.

Just be present, and enjoy yourself. Have fun, dont judge the audience, dont judge your fellow players, and dont judge yourself.
