if it gets to long try 1.5 spaceing cuz it does not look as crowded as single spaceing

you should prob list some of the stuff and then say something like see atached resume for compleate list

and i dont know if theres a way to make it more possive or cheerful but it seems like it could do with a bit more enthusiasim (maybe thats not the right word and maybe theres no way to make fixing books not sound borring to me)
