It's less a system and more just a bunch of sources of truth: 1. Anything that's an event gets thrown in Fantastical (or your calendar app of choice.) 2. Anything that's a todo-item gets thrown in Todoist (or your todo-list app of choice). I like Todoist because it's lightweight but I can still categorize stuff based on loose priority. 3. Anything that's a random note also gets thrown where it belongs: if it's a note about a software project, I'll put it in a wiki/GitHub issue/etc for that project; if it's a note about a person I know, I'll throw it in Contacts, etc. etc. (If I'm too lazy to do this -- which is often -- I throw it in a "Notes" Todoist list which I periodically clean up.) Then, at the start of each day I open my calendar, Todoist, and GitHub, pick up stuff, and write a todo list. Throughout the day, if more stuff comes up I'll write in on the todo list; at the end of the day, if there's still stuff left on the list I'll put it back wherever it belongs. There's still a definite manual component here -- I'm pretty sure OmniFocus has support for a "today view" that handles all of that for me -- but the tactile nature of writing out specifically what I plan on doing helps me get ready for the day a little, and takes all of like thirty seconds. (TBH, I think the core trick with all of these systems is being diligent and disciplined about not letting stuff stay in your head because humans [or at least me] are dumb and forget stuff. Once you commit to capturing data quickly and structuring it in some matter, the rest is an implementation detail.)
