The next time you're convinced that you absolutely must have more space for whatever reason, think of the Carmelite Monks in Wyoming.
Their monastery is literally bursting at the seams, but not because each monk has a personal, luxurious space. They are presented with the pleasant problem of young vocations to the point that the monastery needs to expand.
Take a look though at the personal living spaces of the monks, who are being accomodated temporarily in portable monastic cells. It struck me that the enclosures are not much bigger than some lawn storage sheds.
Sometimes enough is enough.
