This guy's pretty badass:
"Peter Lawrence has few possessions. He can fit nearly everything he owns in a suitcase. Lawrence is a self-described minimalist. After years of living simply while working as a manager for Hewlett Packard - saving much more than he spent - he was able to retire soon after turning 40 and he now spends much of his time working on the internal stuff."
