Should freelancers seek long-term clients or not?

Companies are forced to seek long-term partners (term) if they think to live for years and keep up with all costs.

Are we, freelancers, forced to do the same? Or since our costs are at the minimum and there are many jobs (especially in IT area) we should not stick to long-term clients?

I am not sure if I'm a grunch, but I deal better with new clients, and their projects seems more interesting. With long-term clients, I am somehow "forced" to take any project they offer me, and I cannot reject them by saying that their project "is boring". With new clients, since I only chose projects which are interesting to me, I have no such issues.
