You don't have to eliminate and not do you have to do it all in a single step. Everyone is different and in different situations. Just start doing where you can as best you can. Stop consumerism for the hell of it if you can. Stop following fashion trends and wear clothing until it falls from your body. Don't replace your 5ech equipment because it doesn't have the latest feature etc etc. The statement wasn't meant to be taken so literally and fully.
