Making your goals and dreams public is exciting and probably makes you nervous. What if people don’t like your ideas or think you can’t do something (you KNEW it)? Sharing is risky.
That’s exactly why you should do it. Take a piece of your work and share it with your team. Ask them to honestly assess, or just watch their reactions. If it seems as if they can’t be forthcoming in response then you have a trust problem, not a communication problem. Open yourself up and insist on detailed feedback. This will likely be challenging for everyone.
Model acceptance of honesty. Say out loud that you think honesty equals respect. Ask for it, take it, give it back.
