Good record keeping can benefit young adult ministry in many ways. For example, by maintaining tidy records of past programs and calendars, it will be easy to introduce new young adults into leadership and planning roles. This is vital among a demographic whose leaders and participants are at a transitory phase of life.
Alternatively, keep a journal or Word doc where you occasionally jot down info about the young adults you meet. This will help you get to know your young adults, and it will also help you assess the general trends of the young adult population that you serve.
