E.g. swapping or adding a special colored case during productive time to remind you to return to focus on production when you tend to break into "day-dreaming".
Does not make you start the day, but lets you keep going longer (ok, that might sound wrong, but let's keep it for its mnemonic value).
If I'm wearing it, there's still work stuff on my todo list that needs doing today.
Brings me back to the PC rather than coming in from a walk and doing a bunch of housework I notice on the way in haha. Hard to miss being on my hand, almost anything I could do while procrastinating will make me see it :)
Makes me wonder why I see bringing my phone being a safer bet than bringing my hands :)
It's likely the first port of call when procrastination tries to sneak in (which is exactly why I use it for medication reminders rather than a sticky note or something that might blend into the furniture after a day or two haha)
