This is exactly the same for me—I grew up playing the piano for basically my entire childhood, but it was always a chore. I dropped it once I went to college and figured I'd never pick it up back up, but then I decided on a whim to learn a song I found online. But b/c now it's no longer just for the sake of lessons, it's become a hobby that I really enjoy in its own right (and indeed, all the forced practice growing up has greatly expanded the range of songs that I'm able to learn now).

Same for me, I've learned programming, reverse engineering, music production, cooking, etc. I learned all these things not because I'm intrinsically in love with doing them, I just love having done them. This quote fits it perfectly, "I hate writing, but I love having written."
