Is intelligence something you are born with or something that develops over time?

I was born intelligent but education ruined me. That’s right. No, seriously, how many people does anybody know that can prove this idea. So, I believe that the intelligence is something that a person develops over time. A person grew his believes and ideas while he listens to his family and friends while he is young and then gains more scholarly approach to his believes and ideas as he attend the school. There is nothing like born intelligent. A person’s ideas and intelligence doesn’t relate to his or her parents because they gave birth to him but because he grew up among them. Consequence of a person’s intelligence depends on how he uses it.
