Is it normal to worry that I am too prideful?

Yes, it is normal and healthy to worry about this. :)

A little bit of pride really isn't such a bad thing since it helps with self-confidence. Pride and arrogance can get in someone's way if they are unable to admit to their faults or rage at any sort of constructive criticism - it prevents them from growing. Also, prideful arrogance can be hurtful to others and can hold a person back from making sincere apologies when they've wronged someone.

You say that you are more intelligent than most people you know. Does it prevent you from being open to opinions or ideas that might conflict with yours? Sometimes people with excessive pride can be resentful of those who challenge their point of view. They end up shutting people out of their life who they don't see as being as evolved or enlightened as them.

Accept your own humanity and know that even if you excel at some things compared with others that you still have many faults just like everyone else.
