I thought I was being ridiculous but you loving it is kinda making me love it. 
Maybe just learning some new thing is too easy but if you learn it and add it to Anki then you’ve ensured you’ve permanently learned it and that’s a legit lovie?
I also really like the terms “todone log” and “captain’s log” (HT @malcolm on that). And any enduring thing you accomplish seems like it would count as a lovie.
