I was thinking recently that a lot of people who are in YWAM may have the Peter Pan Syndrome. Socially immature persons in their 30's or so who like to enjoy themselves, like teenagers without responsibility. They may want to avoid a serious job or relationship. They are people who are scared of & don't want to grow up. They want to have adventure & fun. They do not want to loose that sense of comfort.
The 12 years I was in YWAM, even though I was obviously growing older, each new school would mostly have students from their late teens to early twenties, so I was around young people all the time & it did not seem like I was growing older since the new recruits usually weren't. There were students who admitted that they came to YWAM Honolulu for the surfing, not evangelism.
After several years of this one suddenly wonders where the years flew & have nothing but stamps in their passport to show for it. You then realize you have little financially or any marketable skill in the real world.
