I had a similar problem. I now maintain a simple TODO note on my phone and organize the items by priority sections (Now, Soon, and Eventually). I check off the items once I’m done and remove them after a while. This does a few things:
- Relieves the stress of having to remember random stuff that comes up during the day
- Allows me prioritize my worries… the “Eventually” category usually consists of lower-priority things that would have low impact if I didn’t get them done soon (or at all in some cases)
- Gives me a sense of accomplishment when I check off an item
I like this better than the iOS Reminders app since I have more control over various things (with a huge disadvantage of it not being time/date-aware.
I use a similar method, but implemented in iOS reminders. I have different lists for the different categories. And now with a smart list I have created a category/list "this week" that lists actionable items with a due date within the next 7-days. [1] This is loosely based on GTD [2]
