Personally, I think Christmas presents should only be for children. We all receive crap we have no interest in but that other people think we would like and we reciprocate similarly - and most of us would have already bought stuff we really wanted. I'm an atheist but it's a terribly vulgar consumer fest for me.
If you aren't primarily thinking about the baby Jesus simply look at it as a time to spend time with the people you love.
