We all have lots of ideas, about things to do in at our jobs, personal projects we want to start, and life-changing plans. And we question ourselves, asking, "Is this a good idea? Am I sure this is a good idea?"

A much better question: "Does anyone in my situation ever know for sure if they have a good idea or not?"

If the answer to that question is no, then maybe the merits of the idea don't matter so much. Maybe it's worth the risk of doing it.
