I spend about 5-10 minutes a day tracking, usually as part of my daily routine—logging meals, workouts, or sleep at the end of the day.
It’s quick because I keep the system simple (plain text files or spreadsheets), and it pays off when I need to review trends or insights later!
How do you remember a whole day worth of activities? Do you note them down on paper first?
I've been writing about my day every night since 2010. First with a proprietary app which before it folded allowed me to export as plain text then learning Emacs and using org-mode.
You can't capture everything but I've learnt to remember my day.
Apple allows health data export as an XML file.
