Another related one, pass on a project because it just wasn’t something you wanted to do (put ethics, passion, or interest above money)… On the flip side, try it the other way and see how that works out. I passed on a few big projects (disposable floor cleaner and tech exploration program I thought was a dead end) because I wasn’t interested and I just didn’t feel they were ethically right somehow. I’ve also taken a few projects I wish I hadn’t of, only to kick myself halfway in when I was bored but too busy to take another possible project that actually would have been awesome. Live and learn as they say.
