There's a book called progmatic programmes that suggests you have a rubber duck sitting at your desk. And then when you get to a problem or an impasse, what you do is you pick up the duck and you literally talk to the duck, and you explain what's going on. Because you're using a differe part of your brain, like your vocalizing it and your explaining it, actually makes these different connections in your brain. So these are all examples of what you would say slack, or the literature calls incubation,. where literally giving yourself that ability to have breaks is super useful.
