What are our talents?

Some have many talents. My talent is singing. But what about talents that no one has heard before. Like balancing large masses on someone's head. There is also a talent of eating something more that any one, eating a dinnner off a hot air balloon, sticking pins in someone's head, also holding someone else at a long amount of time. Can anything be a talent? Are there some talents that are harder than they sound or look? I'm not sure. I guess someone would have to expirence the challenge to really know for sure if it is difficult or not.

What we know about ourselves

I don't know much about my past, but I know of the present. Being one thing or another does not really make me its how I am or how I feel. I know that I can be hot tempered or calm. I know I can be understanding or closed minded. But for some reason it is hard to admit that in person. How much do we know about ourselves? Is it a lot, just surface, or much deeper than we think? And how is it that others can know as much about you as you do or maybe even more? What do we know about ourselves?
