Enjoyed this list. Over the years I've become better and better at spotting these issues, but even still sometimes it's hard to see them creeping up on you.

The worst for me these days is analysis paralysis. I'm currently working on my own so I don't have anyone around to bounce ideas off. For smaller tasks it's not a problem, but there are bigger design decisions that have ended up taking longer than probably should. When you're left to figure them out on your own it takes a lot longer to convince yourself of the "better" way of doing something.
