I'm going to offer one additional suggestion that may not seem much like reflection, or taking time for yourself, but in the end I think you'll learn a lot from it.
- helping them see new ways to grow the organization?
- inspiring people to do something new, different, or better?
- working with the people the group serves?
- relishing in being behind the scenes?
Maybe there wasn't anything you liked... If that was the case, take another look at why you selected that organization and activity. Then, make sure you ask yourself if you gave it all you had or how you contributed to the success or failure of the situation.
