How come I write things I hate to read, and I can't write things I love to read?

I love science fiction, but I can’t write it. I hate self-help books, and yet I find myself writing advice all the time. What’s going on here? Is it another instance of “short attention span” theater?

I also sort of like personal history, if people can write about themselves in an interesting way. I can sort of write personal history, but only if I do it in one sitting. I reaIly can’t stick to them.

The problem with all this is that I would love to be able to get a publisher interested in what I write, but I don’t write stuff I think anyone would like to see a whole book filled with. I mean, I wouldn’t read it. I find books full of advice terribly tedious.

Anyway, if you don’t love something, how can you do it well? And how come I can’t write the things I love to read? Is anyone else like this? What do you think about this kind of behavior, when you exhibit it?
