One way to think about a micro-action is something we do for about 20 minutes. It's a reasonable approach on days when we don't actually have more time to make progress on what's in our cue.
20 minutes can be scheduled or simply happen as found time. If we’re used to taking as much as we want or think we need, working in micro-actions gets us thinking more crisply about all the parts of tasks. It boosts efficiency and the spaces between micro-actions allows for more creativity, learning and agility.
