I agree whole heartedly. People are far more creative than they think. When we are put into a position of doing with what you have on hand, it's pretty suprising how well you can do. it also lets you know what you really need and what you don't.

I take my kids bare camping quite often and they love it. I challenge them to come up with different ways to build shelters, make comfortable sleeping arrangements etc. It's pretty suprising what an un-biased mind will come up with to a particular problem.
