Right, but he didn't grow up thinking of himself as Kal-El or Superman. He grew up as Clark, first. It's like in the Animated Series, where he accidentally rips off the wing of a crashing plane. He doesn't say "Nice one, Kal" or "Nice one, Superman". He says to himself, "Nice one, Clark".
It's the argument of nature vs. nurture. He doesn't see himself as a superior alien being because he wasn't raised that way. He was raised as a humble, small town, honest, hard working farmboy. The only thing that matters about where he comes from is that's how he got his powers, but it's not how he is as a person.
The thing is, Superman is his disguise. He puts on a strong face for everyone around him, but he tends to doubt himself because deep down, he still has those humble beginnings. He still thinks of himself as Clark, the kid in Smallville who always felt a little different. He would much rather lead a normal life, have a family with Lois, maybe own a farm of his own. But because of who he is and what he can do, he only feels responsible to put on the costume and do what's right. Because that's what he was raised to do. You take away his powers and he's still the same person underneath.
Personally, I see the Clark identity as his true identity. However, he plays THREE different roles: the one of Superman, Metropolis Clark Kent and Smallville Clark Kent. Smallville Clark Kent is who he really is; humble, honest, hard-working, a bit of a mama's boy, total boy scout, a little shy because he feels different from everyone else (something a lot of human beings can relate to). Metropolis Clark is kind of like a pro-wrestler. Some have said that most successful characters, such as Steve Austin, are the ones who take their real personality and just push it a little furhter in the extreme. And that's Metropolis Clark Kent. He's still a good, hard-working guy, but he's also shy, unsure of himself, etc. But all three are always the kind of guy who you can go to for help.

Also, can I just say for a moment that it's discussions like this that make me glad that I came back?
I love you guys so much. You know, in that platonic fellow-Halforumite kinda way.
