I probably won't be able to explain it to you, but I'll try. I'm a complete bookworm. You know Myne from "Ascendance of a Bookworm"? Literally me, except I haven't died.... yet..... I read books because I like to read. Doesn't matter what (well, to some extent it does). The joy of reading is an end unto itself. You're not competing with anybody to get everything written or anything (It's not possible, anyway). You read because you love reading and love stories and love finding new information or just remembering old information you knew at one time and forgot, etc.What motivation is there to do that? I have a modest personal book collection, probably 80+ at this point, and I read maybe 12 of them. I got the time to read them all but I can't bring myself to - there's no will for me to do it. It's easier to just mindlessly watch videos or play games. When you have eternity you lose the pressure that you naturally have of "I have a finite amount of time left, let me do this before it's too late." The only other variable would be outside variables, like another person.
