Best/Worst Experience - Self Published

What has been your best/worst experience since deciding that you wanted to become self-published?

Mine come from only a month "on the job."

My best: Finding out that I sold two copies of a book - and not even knowing about it until I hunted down the book and connected it to my author page. I don't even remember how that happened, but I logged onto Createspace one day, found that I'd sold two books and went crazy. The book is where it needs to be now, though, so no more sneaky sales for me.

My worst: Receiving my first two-star review (I've only gotten two reviews, one was five stars - different books). For a while, I steamed about it because the reviewer wrote mainly negative reviews, but I've gotten beyond that point. I don't care. I'll still write. I've been writing for fifteen years.

So... what about you?
