7. … I think of several things related to work that I really want to remember … as I'm trying to fall asleep …

I use my smartphone (Android) in cases similar to this, though it’s not usually work-related stuff that I think of. I have the sound recording app WAVE Recorder in my dock / quick launch area. If I want to note something for later with the minimum of fuss, it’s easy to unlock my phone, open the app, hit record, and briefly describe whatever it is that I thought of (or hum it, if it’s a piece of music). Then I just hit stop and lock the phone again.

However, the downside of recording audio is that it’s harder to read later. You can’t just skim what you wrote later to remind yourself what you said; you have to wait through the whole recording. This can be mitigated somewhat by giving the recorded audio file a relevant name. But sometimes I value reading the whole thing easily later more than noting the idea as quickly as possible right now.

In those cases, I write the idea down in a new Evernote note. Evernote is also in my phone’s dock. I use the SwiftKey Keyboard to write the idea quickly, and Lux to turn the screen’s brightness below the built-in minimum so that the screen doesn’t hurt my eyes or wake me up too much in the dark room.
