Listen well and be open, because customers and constituents have more information and choice than ever before. If you're not sure, ask them and get feedback. Some of it will be bad, but you will be better off for having had the conversation. Experiment frequently and fail well, learning and getting smarter with each round. As Voltaire noted, the perfect really is the enemy of the good, because if you wait until it's "perfect" someone will produce something more quickly that is merely good - and then iterate fast and often.
