Be Resourceful: Since you are not at the top of your organization you cannot prioritize your initiatives. This often means you will have to be creative and find other revenue streams, other cost savings, and creative options to make your projects happen.
Be Relational: Many times you will not have all the resources you will need to make things happen, so you will have to rely upon relationships you have created and good will you have established with others in your organization. This means you will have to give more than you take. Genuine servanthood will be key to achieve things when you lead from the middle.
Be Resilient: Despite your best efforts, sometimes your priorities will not rise to the top for the organization, or worse yet they do and you fail to make the priority successful. It will happen if you lead from the middle long enough. When it does you will have to brush it off and start looking for the next way you can have impact. You cannot lead from the middle while looking backwards.
