Yep. I just replied at some length in a peer comment. As an entrepreneur, consultant, father and musician I have an extraordinarily busy life and multifaceted set of active priorities, and bulletjournal was a revelation for me. I do a new quad-ruled journal for each month, w/ simple structure: index, future log, month page (w/ a row for ea day, and columns for tracking key items: sleep, run, zen, code, music). I use a nice fine-tipped felt pen to number the odd pages. Then use about a page or maybe a full spread per day, w/ sliceplanner-style 12h clockface in pen (drawn w/ a template I keep in the journal’s back flap). Moleskine Cahir 5x8 quad-ruled (80 pgs) and a GraphGear 1000 0.5mm pencil are both indispensable to me. Having some empty pages at the end of a month means not stressing about writing too much. I can always reference things across journals (eg “bj8p37” or by date). Truly important stuff I retype in markdown docs organized by week. Sometimes I’ll reference docs from journal entries (“cf ~/docs/we171125.md”). It’s not a perfect system but it keeps evolving and so far it’s been instrumental in helping me achieve things in mylife that matter to me — including self-care (sleep 7h, run 1-2mi, meditate 10min) etc.
PS To answer your 2nd Q, a given day has both the radial planner (sized almost 1/2 the page height, used to track passage of time and hard stops / events) and my variation on “standard” bullet journal signifiers (., -, x, >, <, *, $, !, //, o, etc).
