A big extra one is "Are you spending more time pitching your product than building it?" I myself have fallen into this trap in the past and see many others doing it on social media/meetups/etc. Yes, talking about your great idea is great but it doesn't actually help make it happen. I think that this comes from wanting the idea, but not being willing to put forward the effort with the risk of failing. I know lots of smart people who never strive for anything lest they fail.
