Reenacting as "sharing" is a lot more fun than doggedly pursuing "what's in this for me!" Over the years I found that reenactors who enjoy sharing 'knowledge, experience and laughter' with others seem to find the joy they need with an event goes bad. Joy comes from the good times of discovering details which make "history" come alive, from watching a child's eyes light up as you help them discover something they never imagined about history, or from the inner satisfaction of helping a friend improve by encouragement. Hey, God made us to enjoy helping others. Let the curmudgeons grumble about unit politics and rations and campsites. Discover the fun of "gaining" by "giving".
For me, experimenting with making accurate stationery has opened up a spring of personal satisfaction and enjoyable friendships. We don't have to all do living history to the same degree. But consider the possibilities of doing what you normally do in a way that helps others learn -- other reenactors and EVEN spectators. Yeh, I have dealt with the obnoxious kid coming to our tent and assuming everything on display is for taking or breaking. But there have been dozens of other kids who honestly get interested in learning why I'm there and what I'm doing. So take a mental inventory of what you know and enjoy. You might be surprised how much you have to share with others. And you will be surprised how much "giving out" brings in "gains' of joy and satisfaction.
