Have you ever done anything that was stupid or made you look stupid? If you answered no are you being truly honest with yourself? I know for me personally, it seems I am doing more of these kinds of things lately. While some of mine can't really be labeled as stupid,.. they can be labeled as bonehead moves at the very least.
I recently made one of these boneheaded moves on a job.While it didn't have any devastating results, it could have. And that bothers me. I'm going to have to start writing out a checklist for myself on certain jobs and maybe that will help.
I've always been one that when I make a mistake, I'll own up to it and go from there. Making mistakes is human nature. Not learning from them and correcting them is, well, stupid.
