You see the reason I am so interested in math is for foundations. The way I see it, mathematics is the path to absolute truth, or at least as close as we humans may come to it.
What good is truth, though, if it isn't used for something or at least tells us something of philosophical significance? There's beauty in it at times, which is an end in itself, I guess. Not a compelling enough end for me, though, since it can only be appreciated by very few people. Also, it seems to me most mathematicians are creating ugliness, rather than beauty, in the pursuit of very technical questions. Let's face it, if you want to solve a problem, no matter what, you just want the answer, you can't really be bothered if it is ugly. You just have to solve it anyway. But I am not like that. If it's not beautiful, I am not interested and will move on to a different things. There are times when I might put up with temporary ugliness, though, in hope of a better solution later on.
For some reason I have found Algebra less enjoyable than Real Analysis. For starters I feel that Real Analysis and Complex analysis come far more naturally to me, part of the appeal being the ability to visualise things in analysis. However, may favourite mathematical topic so far has been topology, and differential topology (the small amount I have read) seems like a perfect match for me (Is the field still active or has it been "mined out"?).
Yeah, differential topology is the study of smooth manifolds, which is pretty active, still. Geometric topology is the study of manifolds, so differential topology is a subfield of it.
If I do proceed to graduate studies in pure math, I feel the pressure to work in a field just as analytic number theory, with the goal of working on problems such as the riemann hypothesis, yet I only enjoy specific parts of elementary number theory, and am not very good at tricky olympiad/putnam number theory problems. Another field which interests me is logic, but even logic the foundation of all pure mathematics seems second rate compared to number theory and analysis. Is this just an ego or thing or is there something fundamental to these fields that the others lack?
From what I have seen, the basics of logic, like computability and Godel's theorem is vastly more interesting than current research, but that's just an outsider's point of view, having been to a talk or two, and knowing some grad students who thought logic would be cool, but changed their minds what they saw what it actually involved these days. As far as the Riemann hypothesis, yes, that's probably an ego thing. I don't see it as a particularly compelling problem, but then, the only thing keeping me from thinking number theory is totally lame is a sort of duty to think that it's interesting. Baez had a fun post about this.

So, my point of view is the same as that of Baez before he came to appreciate number theory, except that I am aware, as he says, that there might be some interesting theory lurking behind it. So, I sort of take it as an article of faith that it's interesting. "If you say so, number theorists..."
I do like analysis, but I don't have a very good idea what research is going on in that area.
Algebra on the other hand has felt lest intuitive to me, and although I can visualise things, it does not "feel" the same as analysis. Furthermore everything seems less motivated, basic abstract algebra, such as cosets and normal groups annoyed me because I did not understand why we were making these definitions. Would it have hurt for the professor to have given some motivation as to why galois invented the concept of a normal group? Instead I spend most of my time chasing down motivation such as this, only to have exams sneak up on me and forcing me to cram problems and little techniques. Furthermore I have attempted to prove many of the things in my algebra course without reading the text, or going back over my professors proofs looking for better ones, and yet this has no benifit on my grade or even homework. It seems like no one else cares about the proofs, rather solving specific problems in the text or assignments.
Yes, that's just how I was. If you want to spend time doing that, I would recommend not taking a very heavy course load. My courseload in undergrad was a little light after I changed majors, simply because I didn't need that many more classes to graduate, but I had an extra year to play with because I was a fifth year senior after changing majors my senior year. You get in trouble, though, if you care about that kind of stuff. The most interesting part of math just doesn't seem to be valued very highly. I don't know how math should be done, anymore, though. I just know what I find interesting. The subject just seems so big and unweildy as to be completely unmanagable. Even successful research mathematicians feel like quitting sometimes because it's so hard and they feel like they are out of ideas.
Talking about this has made me realize I probably do want to stay in mathematics, even if I won't be the next Terry Tao. It saddens me that you want to leave the field, because I would love to have a professor like you. People like you are the reason I want to go into math, but the fact that you do not find it congenial is very troublesome.
It should seem troublesome. If you care about rethinking old subjects, you're less likely to get far with research. The people who just want to pounce on the homework and don't care about anything else are probably the most likely to be successful. Those who just take a lot of theorems on faith and get as much work done as possible. That's what is rewarded.
