Gibran Vita makes every effort to get rid of the dispensable. He lives in a small home and wears extra layers indoors to cut his heating bills. He eats and drinks in moderation. He spends his leisure time in "contemplation," volunteering or working on art projects. "I like to think more like a gatherer, that is, 'what do I have?' instead of 'what do I want?'" he said.
