One definition of burnout: "trying to walk in another man's calling." (Mike Bickle quoted by David Ravenhill in The Jesus Letters.)

David Ravenhill writes on p. 157 of his Jesus Letters: "According to a recent survey, 70 percent of today's pastors would leave the ministry if they had another way to support themselves and their families. Seventy percent of all pastors constantly experience depression."

Can this be true? I'd like to hear some feedback on this statistic!
