This is a rather absurd column, from Cary Tennis, but the first bit of it is so thoroughly true and amusing at the same time that I not only added a piece of it to my quotes collection, but felt the need to include it here:
How can you expect to enjoy life without heartily disliking a good many people? Do not be afraid to dislike the people you dislike. Disliking people is an oft-neglected pleasure. People have so many dislikable traits, it is a terrible waste to miss out on disliking them.
