"If I don't do a (standup) set in two weeks, I feel it.

I read an article a few years ago that said when you practice a sport a lot, you literally become a broadband: the nerve pathway in your brain contains a lot more information. As soon as you stop practicing, the pathway begins shrinking back down.

Reading that changed my life. I used to wonder, 'Why am I doing these sets, getting on a stage? Don't I know how to do this already?'

The answer is no. You must keep doing it. The broadband starts to narrow the moment you stop."
