Another "hint" is that I use a cheap plastic business card holder as a base for my phone at night. It becomes my sideways alarm clock. Not so great a hint, but I had some left over from work.
Oh, and another one that I always do... In order to know which earphone "L" or "R" belongs in which ear, I put a simple knot in the left cord under the earpiece. That way, I can feel which one belongs in which ear or take a quick look (and not have to search for the tiny letter).
