Yes, I have a printer with both RJ45 and USB. I spent a bit more to get that, so I can stay flexible depending on what I want to do with it.
Absolutely brilliant. It's so stupid (in that it's kind of silly how easy it is to game our mammal brain) but I can absolutely see this giving an extra kick of motivation.
Have you heard of the INCUP model for ADHD? Interest, Novelty, Challenge, Urgency, and Passion. The more factors an activity has, the more drive the ADHD mind has. Rarity system adds novelty and a bit of passion.
Also if you have looked into operant conditioning at all, you know that variable interval reward schedules are the strongest behavior-forming systems (hence, slot machines and every game that act like them).
As for variable interval rewards, I knew about the concept, but I did not include it in the article because it is already too long, and also because I have not yet found a smart way to use it in my productivity system.
Maybe it'd be fun to combine this with your receipts, where random tasks reward points to earn prizes.
Or maybe this is just more procrastination!
Well, what is life but procrastinating on death?
