One thing that often happens with me: odd hour wakefulness focused on organizing. Not out of any sense of anxiety, mind you. Rather, my brain comes alive with ideas. I find it amusing.
My current focus when it comes to personal organizing: realistic daily loads. I've been using what I'll call a "day dump". I throw most of my outstanding workload into "today", then shift the un-done into tomorrow. That's quite frustrating. It makes it look like little gets done. And organizing starts to take much longer, especially as time oases. Plus, when you scroll thru a huge task list, it's easy to get overwhelmed.
I'm trying my best to build my task list into something that has a real chance of getting accomplished. Helps keep my main foci on page one, and not scroll around looking for sheet I should do next.
