I recall there have been several threads basically discussing "what do I do with all this free time?". Much of the responses were along the lines of "I cannot imagine not knowing how to fill my free time.....I have so much to do.....you must be a loser if you are at a loss".
So, this is not one of those. But, my experience is that I cannot do all that I might due to family circumstances. I have two kids that are 14 and 12. My wife isn't as comfortable with the FIRE (doesn't complain, but views it differently and is more cautious), and went back to work full-time last September, and almost full-time about 6 months after I quit.
I live in the 'burbs of a large city that is not that interesting. Moved there for the particular industries. We are not moving to avoid uprooting the kids as they enter high school. So, the caution is that, while I have a lot of free time, I am not able to do all that I'd like. Frequently traveling by myself would not be fair. Summers are great, but the other nine months is, well, sort of boring.
My warning is to not FIRE while you still have kids unless you live in a fairly interesting location. Perhaps quit the stressful corporate job, but plan to work to fill the time until actually free to do whatever.
I'm firmly in the camp of "too much to do all day".
Having said that, here's a thought experiment:
Do you have to be in a certain location to be happy?
Or from another perspective, if you move to your dream location are you sure you'll be happier than you are now?
What if you go through the whole uprooting relocation process and learn that the new location has just as many problems-- different ones-- yet still about the same stress level?
Because I've learned that lesson many times through my career. My spouse and I moved 13 times in 20 years.
The military has a cliché: "Bloom where you're planted." You've made a location choice (for perhaps the best of reasons) but during the next few years you could work on matching your interests to your location-- or better still, develop your location-free climate-independent interests.
When you reach financial independence, you have to be responsible for your own entertainment. You can't merely depend on the corporate offices, or your family, or your environment to provide it for you.
I hate the feeling that I'm just waiting for the kids to graduate high school so that my real RE can begin (in 6 years).
Speaking as an empty-nester looking back on those years: "Ha, that's pretty funny!"
When our daughter graduated high school and left for college, we still found ourselves still constrained by the "school" schedule. We tended to stay home during her winter/summer breaks, and we did most of our traveling to her college (family weekend, sports events, summer school, graduation). We took one trip abroad with her, but in retrospect she was still tired & stressed from exam week and didn't appreciate the travel (let alone doing it with her parents) as much as she could have. During breaks it was better for her to recuperate & reconnect at home.
When she graduated from college and launched from the nest, we were finally free to travel the world. So you know what we did six months later? That's right, we visited our daughter. Admittedly she was stationed in Spain and had an awesome launch pad for day trips and weekends, but we still made our plans around family.
As unappealing as life with teens may be, it will eventually get better. You can make it better now by figuring out how to improve the balance between your parenting and your personal life. (Your kids probably don't want to be seen in public with you anyway.) One day you'll look back on this time spent with them and appreciate the value. You won't want to repeat it, but you'll be glad that you made the most of it.
Our daughter's 23 years old, and this will be the first year that we've done lots of travel without her.
