I agree, it is so important to have something that feeds your soul outside of your call as a Chaplain/Minister.  I love photography and it is a spiritual practice for me.  Over the years, I have kept solid boundaries and I truly believe in keeping those boundaries,it has sustained me and has given me longevity in my call.  My boundaries are not always welcomed by others, however I understand that has more to do with the other person than myself.  I am finding in this New World Order as I am calling it, that it is even more needed to have a spiritual practice, something that feeds your soul, because now the everyday task of going outside of your house can become stressful in addition to the everyday work stress, which we encounter.
