Small unfinished tasks like unanswered emails or package returns drain mental energy even though they take less than 20 minutes. The speaker calls these open loops and asks you to notice which ones are stuck in your head right now.
An open loop is a task under 20 minutes, so not longer. It's not like a big project. It's a small thing, 20 minutes, that's been nagging you for weeks. So maybe it's an email, a package, a form, a call, just something small. So think about what is actually nagging your energy, a quick little drain, maybe a return of a package or whatever it is on your end. Now I want you to not do it yet. So I just want you to name it.
