After years of hiking and camping with Boy Scouts, I came to this realization:
"If you don't have it, you won't need it."
It's suprising how little we need to get by. Having spent our lifetimes in an era of realitive wealth and comfort, our species is still amazingly hardy and has but a few basic, easily fulfillable needs. I've found that, proportionally, the hiker who has very little, and makes do with what he has, or is ingenuitive with what is available to him, is happier than the hiker who carries everything, but is weighed down.
