It's okay to take a break to clear your head. It could be an afternoon, a day, or a week, but sometimes you just need to get away from the situation long enough to gain a fresh perspective.
Periodically take a solo retreat. Occasionally I’ve taken a night and a day at a local retreat center. I’m usually the only one there. When I go, I think, pray, plan, write, and study. Those periodic getaways refresh my soul and help break me from the rigors of ministry, resetting my focus to respond appropriately to the stresses ministry brings.
