We’re dressing up here for Halloween, regardless of whether we can actually go trick-or-treating. Even though we aren’t going to be able to be on display for the neighborhood this year, it’s funny to think about what the act of dressing up does: it gives you permission. All of the sudden you can act in a different way and it’s ok.
I previously mentioned that you should get a helmet. Using props, dressing up, pretending for a moment to be something else, all of these are good tools you can use to trick your brain into forgetting the fear of failure and ridicule just enough so that you can act.
