Another irritating sample:
I particularly want to point out the following little bits and pieces:
More importantly, in this particular case, the narrator is an extremely self-assured individual, to the point of outright arrogance. She's the kind of person who assumes that her supposition about any situation is correct, without even thinking about it.
Even writing with a more reticent character, though, there are crisper, and more varied ways to seed in a little doubt than just using the word seemed every time. The character can put his or her uncertainty into the form of an inner question, perhaps. And it's okay for a character to jump to conclusions. In fact, it can make the conflict jump ahead in leaps and bounds, or add small, subtle layers to the trouble you're already building.
I'm also a recent and enthusiastic advocate for Mark Twain's advice about the word "very".
Here's my revised paragraph (for a future re-print of the book).
I'm glad I'm aware of my seeming problem. Or, you know, my very real problem. So much that I'm going to be specifically doing word searches for "seem" in all my future editing passes and, 4 times out of 5, finding a simpler, better, or just plain different way to say it.
