I have a minimalist for more than a decade. The hardest part is convincing others to become more environment friendly. I couldn't change even one person.
I mind my own business and don't give a shit what happens to the world
you are first and foremost responsible with how you live your own life, not how others live theirs. However, how you live does change the life of others around you (however miniscule it may be). Thus, you did the most important thing and that's respectable. A single person might not change the world but anyhow can make the world a better place.
