"Wise time management is really the wise management of ourselves."
-Spencer W. Kimball
Effective teams have a process for managing their time. There are many tasks to do, many things to learn, and at the end of it all the team members are still just kids. Having a process for managing time during the meetings is a wise practice. Ideally, the team leaders (kids) will decide what are the key points to cover in a planning meeting. This will change throughout the season.
The process of time management has a few key points:
1) there is a youth leader or leadership team that (helps) set the direction for the team.
2) the leadership team regularly meets to plan what needs to happen
3) meeting agendas are developed and used
4) a team member is assigned to manage the time and activities during the meeting (which doesn't need to be one of the leaders or even the same person for each meeting.)
