Dyslexic (positive points) You have a lot of difficulty with reading and writing, therefore: - reading skill books takes longer - literature is less effective at reducing boredom/stress/unhappiness Bookworm (negative points) You are fascinated by books and obviously read a lot, you are able skip words and still understand sentences, therefore: + reading skill books is faster + literature is more effective at reducing boredom/stress/unhappiness The factors longer/faster/less/more can be defined so that they do not make the game a lot more easier. (You could also theoretically have both traits, which would give a "reading bonus" of certain level, where the tradeoff for trait points could be tempting) (Offtopic: English is not my first language and I may, myself, appear to be dyslexic. I can assure you this is not the case. I'm not a bookworm either, though )
