I had a rare form of cancer when I was 22. THAT's what made me aware of my own mortality and lead to the dream of FIRE. The cancer had a "propensity to recur", so I made sure to enjoy the journey and celebrate all the good things along the way. I live in a very HCOLA, and MMM didn't exist then to show me how, so it took way too long. I finally got to FIRE, but I also traveled to the weddings and to see the babies and a good part of the world. I bought nice homes, clothes and generally looked to an outsider as if I was spending everything I earned, but I secretly wasn't.
Best of both worlds, IMO.
Last weekend was my 41st HS reunion. What a hoot! There sure were a lot of old people there, lol.
Finally, to answer your question more specifically, no. On any given day, I cannot imagine exactly what life's going to look like in the future or when I'll get to the end. I just rest easy knowing I'll have enough money to handle whatever it is, whenever it happens.
