Regimentation
If you have difficulty taking supervision and enjoy being self directed, the military could be a difficult choice.
When I was growing up unruly boys were sometimes sent to the military to learn dicipline and become "men". Often it worked, sometimes it didn't. I think nowdays if you don't fit in they are more inclined to fire you.
Like it or not, it is for a specified term and you have the oportunity to learn valuable lessons about follow-through.
