It depends on the person, how well I know them, and how receptive they seem to the idea. I don't talk about money or savings unless people ask me for some form of financial advice. For example, when a coworker recently out of college asked if I signed up for the 401k program, I told her I only put in enough for the match for now and will start doing the full $17.5k federal limit after I pay off my loans. She was like "wow, that's a lot!" I just said I want the flexibility to go on super long round the world trips when I get older, and the sooner you start saving the more valuable it becomes over time. Enough to spark interest if it sounds appealing to her but no need to disclose FI plans. In the cases where I do disclose it, I'll usually say I'm aiming for age 45-50 instead of early 30s, and usually only with good friends. I don't tell family, I'd rather tell them I work online after FI (and I probably will to some extent) so I don't plant ideas about being a free source of loans when it comes.
