I'm looking at the projections for my savings and I should achieve financial independence in just a few more years. I'd be mid-30s. I've talked it over with the spouse and neither of us are quite sure what to do with the time. I've noticed when I have too much free time, I get less done on personal projects not more.
What would you do with the time?
Would you work a part time job? Start a contracting or consulting business?
Enjoy time with your kids?
My suggestion would be to stop viewing the FI threshold as some sort of life changing event. You won't suddenly check your bank account one day, realize you're over the threshold, and suddenly feel fulfilled and free of your need to work. In fact, I can tell you from experience that it's a bit of a non-event.
I suggest you continue working until you have some idea of what else to do. Leaving your job is technically fine if you're truly past the FI threshold, but only if you have something else to do. You'll fine that there are a lot of hours to fill in a week without a job.
Traveling can be great, but unfortunately filling year after year with travel is likely to greatly increase your spending. Ironically, this can actually move you back under the FI threshold for a lot of people. It's a common mistake to calculate FIRE thresholds based on frugal spending when you're occupied by a job all week, neglecting the fact that you're going to be spending more, not less, in early retirement.
