I like to cook a lot, though I don't get to do it as much as I'd like. I don't make a lot of things -- I'm very much a habitual eater, and don't mind having the same things for a week or two straight. But what dishes I make, I make well, and I'm confident I could make anything else if I wanted or had to do so.
My mother always says that "if you can read, you can cook," and I subscribe to that, too, although I do think it takes a combination of touch, talent and experience to do it well, and with really tasty results. My mom and grandmother were both excellent cooks, and they pashed down that interest/skill to virtually all of the next generation.
All of my brothers are good cooks (one is a trained executive chef and restaurant/hotelier business man and one an expert on the barbecue grill), to the point that it is they, not their wives, who do virtually all of the cooking in each of their families. My mom, still old-fashioned in that way, frequently shakes her head in disbelief and laughs about that.
