I started thinking about the evolution of my personal information management systems from 2001 to now. Rough timeline:

- 2001: university: assignments, class notes, projects; Planner Mode in Emacs (daily tasks/notes, category notes, blog with RSS feed)
- 2003: teaching: lesson plans, notes; Planner Mode
- 2004: internship in Japan: language learning; Planner Mode, flashcard.el
- 2005: master's degree: research, class notes, finances; Planner Mode, Ledger
- 2007: sketchnotes, working at IBM: internal vs. external notes, publishing to internal blog, moving my public blog to WordPress; Org Mode, org2blog, WordPress
- 2012: self-directed learning - what do I want to spend my time and energy on?; time tracker
- 2015: Emacs News; categorizing Org Mode list items
- 2016: parenting - sleep deprivation, interruptions, limited computer time; MobileOrg
- 2017: web-based journal so that I can easily update it when traveling without my computer
- 2018: switched from MobileOrg to Orgzly
- 2019: EmacsConf; Org Mode for scheduling and automation
- 2021: switched from WordPress to the Eleventy static site generator to reduce security things to worry about
- 2023: SuperNote A5X - easier black/white/gray sketches
- 2024: starting to have more predictable focus time, can revisit my Org Mode notes and projecrs; WhisperX for audio braindumps

@sacha
This is really great!
Thank you for sharing this - you‘ve got answers to questions I didn’t even know I‘ve had :-)

@gerritbeine oh, what questions occurred to you? :)
