I haven’t figured out how to write about this without it feeling too squishy, but spaced repetition has been a really interesting venue for experimenting with this sort of feeling. I have lots of prompts whose primary purpose is reinforcing my emotional connection to a person, or a place, or an ideal, or an idea. It sometimes feels like a misshapen emotional crutch, but sometimes it feels like it expands my capacity to love!
