I attended my first “time management” workshop back in the early 70s. I got the bug pretty bad. Read and listened to countless books and cassette tapes (before CDs) on productivity. I think there was a recent resurgence under the GTD (Getting Things Done) banner. Somewhere along the way, my passion waned but in those 35+ years, I’ve tried lots of tools and systems.
To-do lists have always been a challenge for me. I tend to put too load them up with too many items and they stay there too long. I recently came across the notion of identifying three things you really want to accomplish during the day and writing those on a 3×5 card. Portable, focused… might work.
My current favorite is the Tasks applet in Gmail. Small, simple and available everywhere. Supports multiple lists. About as close to that 3×5 card as I can get.
