Well, to me, the content lies not in buying lenses but in seeing those nice shots i always wanted to produce by myself. But as a newbie after taking up photography for some time, the kit lens' limitations tend to weigh down quite heavily so i guess thats when the urge of buying lenses to complement your needs comes... As long as I get sufficient lens for telephoto, wide angle, fisheye etc to access differnt levels of photography, the only thing left to content is to get my photos right! =]
