How to set up automatic rotating reminders in my everyday environment?

The Problem: I have tried sticky notes, DIY jack-in-the-boxes in my pill jar, Chrome add-ons (Kill Procrastination is a fun one), and otherwise run the gamet on designing my environment to remind me to do the various things I should be doing more often but don't think of.

And yet, without fail, I ALWAYS ADAPT TO THESE REMINDERS AND SOON GO BACK TO MY FORGETFUL SELF!

Do you guys have any suggestions for rotating reminders? I mean, for the first week or so of every novel little trick, it works. It's just when it's been there too long that it fades into the background.

I figure, if there was some way to switch it up automatically, then I would never have any one reminder in the same place long enough to adapt to it. Every day, my relatively new reminder would b e noticeable.

I say my "everyday environment" broadly. Anything I will see everyday. My iPhone background? Desktop background? New tab on my browser? Bathroom mirror?

Is there any app or life hack you guys know of that would let me switch up a message wherever I'd see it, frequently and automatically?

VueMinder Lite is free and provides a desktop calendar for Windows, so you'd see all your reminders and upcoming events every day (assuming you use your computer every day). See the link below for more details:

VueMinder Lite also has a plethora of reminder settings with even more in the paid Pro version. For example, you could have a certain song play when the popup reminder appears or a text-to-speech voice can provide the reminder details. The Pro version can include web pages, pictures, videos, etc, as part of the popup reminder. There should be enough variety there to keep you on your toes!
