I can't say I understand what it is like to be bored personally. Over the years, I have often wondered if this was just some word people throw around with some other meaning. At times I thought it might be due to children being spoiled and not having experienced times without someone trying to keep them occupied. Other times, I thought it might have to do with too much early exposure to TV.
It also occurred to me it could be a lack of creativity. I have always been able to find some way to find entertainment in whatever situation I found myself in. My DD6 is also very creative and for the most part able to find a way to entertain herself. However, there is a difference between us. As soon as she is done an activity, she goes instantly from happy to unhappy. Whereas I continue to feel good for hours or even days after the activity is over.
I used to say a lot of people do not know how to savour the good times. My new view is this has something to do with more instantaneous changes in emotion. This does not run in my family, but it definitely runs in my daughter's mom's family. Not only do they have these instanteous changes in emotion, they have extremely intense emotions.
At least in my case, my DD is creative enough to make her own fun. However, the rapid emotional changes does worry me somewhat.
I've kind of gone from looking at this from a nurture point of view to a nature point of view. I am still open to nurture having some influence on this.
