Poor Judge

You ever look at something you wrote, say, a year ago, something you thought at the time was pretty good, and realize it kinda sucks?
Ain't that a drag?
Conversely, do you ever re-read something you wrote a while back that you thought sucked at the time, but it turns out it was actually not bad at all?
Not so much of a drag.
But I swear, I'm the absolute worst judge of my own work sometimes.
I was looking over an old story I wrote-- in fact, it was the first story I ever sold, a peice called Battle of the Carson Hotel... started cringing because, well, it's not a bad story but man there are bits that are just sloppy ane embarrasingly amatuerish.
And then I started going over this novel I had begun a couple years ago called The Scarab. It was something I'd given up on almost 300 pages into it, because it felt awkward and pointless... but, reading it now, with all the fine details gone from my memory, I found myself actually enjoying it. Turns out it's actually pretty damn good.
Does this happen to anyone else?
