For years, when I needed to jot down a note I wrote it on my hand, laughing it off by saying it was my Palm
Pilot. Sadly, the decline of Palm has made this joke anachronistic while the practice of writing on my hand has just made me look pathetic this far into my 20s.
However, these Post-it notes
cut into the shape of watches by PA Design
are a cute, useful, and discrete way to keep reminders in sight at all times. Sure, they might also make it look like you just broke out of the mental ward, or perhaps an all-ages rock show, but that's a small price to pay for utility.
