1. Remember to keep a list
2. Remember to update the list
3. Remember to check the list
4. Start a new list because I can't remember if / why I care about anything on the old list
(Personally, I've never started a list but I can imagine how it would go.)
On balance, this shift in my attitude means I definitely use more simple organizational tools more often than I did in the past, and that has certainly helped my productivity.
* Christmas / birthday ideas
* House TODO
* Project ideas
* Car maintenance
I'm always writing emails, and I notice that I've got things in my drafts folder, so it reminds me to keep it updated.
