An ex-co-worker and I remained friends after he left the company. We've always batted around investment ideas, 401(k) contributions and the like, but he has always been a bigger spender, but no McMansions and only one BMW that he sold after the first trip to the shop. So, a couple weeks ago I tell him that I am going to RE next year and his competitive juices started flowing. He asks me how I did it and I tell him about my 50%+ savings rate. I send him links to MMM, MadFI, and a few others and tell him to start reading. He has been calling me up every 4-5 days to update on progress. Just got the latest update. He did a post-mortem on his last 12 months spending, was utterly shocked, and has been making as many changes as he can. He developed a new budget and spent 2 hours looking over everything with his wife. They both came from modest means, hate debt, but just let hedonic adaptation get the best of them as they progressed in their careers. I really feel like they could be FI in a decade or so if they stick to it. Even worst case senario, they will be far better off than if they had done nothing. I am really excited for them!
