Good for him but i find this kind of free-wheeling and 'zen' lifestyle very selfish at its core. Go minimalism to what end? Why don't you do something that contributes to tree of human knowledge or something makes humanity more efficient?
And yes, it is very selfish. I try to optimize for my own happiness. Which includes helping others, being nice, adding value, doing things that make life less fun in the short term but better in the long term.
