I probably don't have the patience for knitting or crocheting...or sewing..., I love poker xD but I'd rather not lose money =p, andd I like to read and write, so there's reading...as far as writing goes I get too many ideas so I can't hardly finish anything >.>, and I don't have much time for any volunteering seeing as I work all week and then my weekends are filled too.
read manga ^.^ or if u wanna expand your vocabulary you could always read some novels... sports are nice if ur into that sorta stuff
its hard for others to help you since hobbies are subjective
