Pocket notebook. Some pages have notes of stuff I think about during the day (for future goals). Mostly, though, I have per-day todo lists. I leave a blank line between items to add optional metadata later, like scheduled/due time, category, time estimate, when I started and when I finished. I chose paper media because it makes it easier to experiment with different formats. The pocket form factor allows me to carry it everywhere. When I want to track my goals and progress on a software project, though, I opt for org-mode in emacs. It's mostly because it's faster to type than to handwrite and staying on the computer keeps me in tune. Also, it gives tremendous freedom to organize notes and tasks. There's a lot of features and minimal clutter despite that. It's too bad it's lacking a good android app.
