I know this and do this, but I would add, make sure you _actually_ read the error message and don't _think_ you read it. This bit me just yesterday as I was encountering an issue and spent a good 30 minutes trying to solve a problem I thought I'd been having. When I re-read the error message it was clear that I'd been too careless and not fully understood the issue. It happens from time to time and then I'm more cautious for a while until I get _just_ complacent enough to have it happen again.
