wow, where to start. I'm going to try to not be as condescending as you, but it might be tough.
First instead of spending a lot of time worrying about every penny I spend and every penny I can't save, I'm going to put that effort into my career so when I am your age the thought of shopping at a Walmart to save some money is laughable. truly laughable.
In my world, life is all about making choices and having ideals. So goodluck living in your world but in mine I will stick to my decision to support local businesses and be proud of it. yea, this world is not perfect and I am only one person, but this one person is going to use his brain and his instincts to make decisions and be happy I did.
thank you for your post as it has truly inspired me and amazed me.
