While I was working I mentored a lot of fresh college kids. I always told them I had an open door policy and if they ever needed to talk about anything, just set up a meeting or lunch. During my first meeting with them, I would talk about the typical career stuff, but I would also spend about 10 minutes discussing financial planning and how to maximize the benefits from our company. Many of them set up monthly or qtrly meetings to discuss careers, but a few of them wanted to talk about financial planning and investing. I had several colleagues do the same. I would not discuss FIRE openly unless people showed interest and asked questions.
My brother was super excited for me when I first talked about FIRE, but when I talked about spending less than you make and investing the rest, he flipped it and said I made more than I could spend. That was about 10 years ago and now I am helping him budget and he gets it.
I have a great friend who is about 7 years older than me. He used to be my boss/mentor he retired at 50. Him and I still hang out. I have another buddy who I lived with before marriage. He is a year younger than me and retired 3 years before me. I look up to him and we have always talked about investments. This forum has also been helpful, because there are things that I have discussed here, that I haven't even discussed with my 2 retired friends.
My old boss has no kids but is into charities and giving to the ones he is passionate about. My other friend has 4 kids and we talk about how we want to make sure our kids turn out to be great adults with good careers that make them happy. I have another friend that is a year older than me, did way better in his career than me and my friends above. He invests wisely and is probably worth close to $100m. He is still working and says he won't retire until his kids are done with college in 5 years. I don't understand why he is still working and he probably doesn't understand why I retired so early. To each his own, but we are still friends.
You are in an enviable position. The key is to find a couple people that share your enthusiasm, stay humble and understand that some people will get it, but most won't. Keep in mind that there will always be people that made more, saved more and had/have opportunities that you don't. And that is ok. Live your life and do things that make you happy.
