Reading physical books

Hi guys, I’ve mostly been reading digitally (first Satori Reader and then Manabi Reader, recommend both). I wanted to take a stab at physical books, idk if I’ll regret it lol but I wanted to try anyways. For people who have done it before or who do it frequently, I was wondering how you go about looking up words you don’t know especially when the book has no furigana. I am aware this will probably be a pain point so if you found a way to make the lookup process easier I’d appreciate if you share. Thank you!
