Look up the term Exobrain[0]. It's related to externalism[1], defined as: "Externalism, the philosophy of the mind's existence outside of the brain and body". > The extended mind model suggests that cognition is larger than the body of the subject. According to such a model, the boundaries of cognitive processes are not always inside the skin. "Minds are composed of tools for thinking" (Dennett 2000,[23] p. 21). According to Andy Clark, "cognition leaks out into body and world". The mind then is no longer inside the skull, but it is extended to comprehend whatever tools are useful (ranging from notepad and pencils up to smartphones and USB memories). This, in a nutshell, is the model of the extended mind. Note taking is my 'other brain' that I use to get things done. I casually glance at past notes, and am often shocked how much progress I've made all due to these notes. I don't get everything done, but that's not the point. The point is to get thoughts out of your system and into notes so you can organize your life better.
