Here's the thing, he grew up as Clark Kent. He didn't find out about his powers until he grew a little bit. Its like being adopted from another country. Just because you found out you were originally born in China doesn't mean you're going to stop being an American. You are definitely going to want to discover your roots and feel more pride of your heritage, but fundamentally you don't change who you actually are.
"Superman" came about because Clark wants to do good. He wants to help the world, use his gifts as a blessing. It doesn't mean he has to stop having a real life. Don't you think being a reporter, being a son to the Kents, or being a boyfriend/husband/in love with Lois is just as important as his other "job"?
Read Superman: Birthright.

As much as I hate to reference the show Smallville, they nailed that pretty well. He learns about his birth, his heritage, his powers, but becoming Superboy/Superman isn't something that just happens. Its an evolution of his desires to do good. An outlet to help people.
