Is It OK to Keep It in the Same File?

I always do them in the same file just for my own sanity sake, especially if I'm trying to teach something to people. If I need that thing more than once, I will put it into its own file and import it imported in. But in a lot of cases, you only need it in that one file. And you're really not reusing it all that much. So I think it's totally fine to put it in thesame file. Which I think makes people who love rules Twitch, because people always ask me like, what do you do? And I'm like, kind of bit of both.
