Turn organizing into a social affair. Consider organizing a clothing swap, or a book swap. Invite your friends over to your home one afternoon or evening to bring clothes that they no longer wear or love or books that they have already read, and try swapping with one another. Whatever is not "claimed" by someone else at the end of the afternoon or evening donate! What a fun way to have an evening out! Swapping can turn into a monthly event. One month clothes, another month the worst  ever received and never used but felt too guilty to give away.
