I like to eat a variety of things (now-- I didn't always).
I do also tend to enjoy consuming the same things over and over. It is easy to do, and saves the effort of constantly coming up with something new. I enjoy the comfort of known tastes and textures. I enjoy the simplicity of choosing from a relatively limited menu (and also find that it is easier to get my kids to eat if the choices are relatively few).
I do, however, eventually get tired of consuming the same half-dozen meals over and over and over again, and then must go back to my wider repertoire and pull out a few "new old things" to wear out in rotation or resort to my shelf of cookbooks to find something truly new.
When I was a kid, I lived on the same small handful of foods for about a decade. Fortunately, meat, carbohydrates, fruits, and vegetables were all represented, if only in very limited variety. I owe my grandmother a deep debt of gratitude for all the years she spent preparing a separate dinner from the few things that I would eat; all I can say in my defense is that at least those few things were simple, cheap, and quick and easy to fix. I think cubed steak and fried chicken drumsticks were the most difficult things on a very short list.
