There were only 3 of us sitting at lunch today (devops were all in a lunch-and-learn elsewhere). Had a lovely discussion with my two colleagues regarding retirement, investments, etc. One is already pretty mustachian, I'd already spoken to him about it and I've introduced him to MMM.
The other is currently getting out of debt (poor decisions in his twenties along with being a freelancer with no financial discipline). This one told us about his strict new budget with his new live-in partner, how he's using the snowball method to pay off his debts, and will then be rolling those equivalent payments into what he can save for retirement and for his little girl's education. He didn't really understand what our company's retirement package looked like, what certain things mean (like MER), and what not, but seemed really interested when we explained these things.
Just sent him MMM and Canadian Couch Potato, and he said "thanks so much, I'll read this this weekend for sure!". Baby steps, but I think it's awesome for him.
Becoming interested in these things is the first step.
