Your Vision

What is a vision?

Your vision answers the question "What do I want?" A clear vision help you communicate why you're here and what impact you're going to have.

Your vision should be aligned with the company vision, with your manager's V2MOM, and it should be personal. It should be an honest reflection of your own vision for your own work.

If you manage a team, it should be reflective of the purpose of the team and your collective impact.
