I honestly don't even know what you're trying to ask here.

For argument's sake, someone who's normal is a functional member of society without major mental or physical health issues, a criminal record, or notable achievement that will result in them becoming historically known. They have a roof over their head, a reliable mode of transportation (public transit or biking included), and a steady income of sorts. 

Since people's interests differ wildly, you can't really say their hobbies or interests are abnormal unless it's something that most people would find unsavory or off from what's generally socially acceptable, for instance going down to Rusty Joe's Meat Locker and suspending yourself from meat hooks for your Saturday Night or doing hard drugs to cope with whatever on a nightly basis. 

Since people's personalities differ wildly, unless there's something about them that prevents them from being able to function in public and among family and friends in a manner similar to most people, then the norm would simply be that they're acceptable. 

Normal people can still do extraordinary things, we aren't defined by a single action unless it's something that's been building up for a long time. For instance, a lady who fends off a chupacabra from stealing her kid when they were going for a walk is still a normal person, she just reacted to something. Some famous military conqueror or serial killer who spent most of their life working towards what made them famous is another story. 

Really, the vast majority of people are normal and probably unremarkable, even if they have talents that others don't. Normal is good; it means society is working. A person's value isn't based around how normal they are, it's how they effect their friends, family, and community that really matters. It's not overrated or elusive, it just is.
