That is uplifting. I recently got two conference papers rejected, and I was a bit downcast about it. It's nice to be reminded that individual failures don't tell you much about long-term success.
I've given up worrying about conference paper reviewers. The last paper I submitted got a strong accept from one, and a reject from the other (the overall decision was accept). Interestingly the reasons for accept/reject were almost exactly the same - the stuff one guy liked, the other guy hated. It's completely luck of the draw, so don't be disheartened.
In any case, I pick conferences largely based on their location (if I can get paid to go) rather than their academic merit. That's what journals are for!
If you need some morale boosting, come talk to me about conference paper rejections (I can't speak publicly of this). I can tell you of at least three separate best paper award winning papers at the absolute top conferences where the drafts spent 1+ years in various rejection bins.
Ah, conference papers.. I had my share of rejections, got a paper rejected in 4/5 conferences, but in the end it got accepted in a good-enough conference!
In retrospective, I think every single paper I wrote was rejected at least once, but I always read carefully the reviews to try to improve them. For what I can remember, many reviews were about little stupid things which I just interpreted as the reviewer "didn't like it".
Keep on going, but know when to quit. At least two papers I wrote didn't got anywhere and I had to throw them out the window..
