You've got to begin doing the difficult things that help the team to improve and develop high morale. Among other things, you must:
1. Make changes that make the team better.
2. Receive the buy-in of team members.
3. Communicate commitment.
4. Develop and equip members for success.
The two toughest stages in the life of a team are when you are trying to create movement in a team that's going nowhere, and when you must become a change agent. Those are the times when leadership is most needed.
