My wife and I have been open mustachians for two years now! Since then, we have nearly paid off a car, saved a ton of money for a house, and went from general contracting our house to being the actual contractors. Pretty much everyone thinks we are crazy!
Yesterday a younger friend of mine got his first job with an "adult salary" (his words). He came over and must have asked a hundred questions about investing, automatic savings, budgets, etc over three hours. It felt awesome to share this knowledge and actually have someone else get excited as well!
