I dropped back from full-time to 3 days. Much as I would have loved to leave altogether, I just wasn't game in the end to risk not finding work soon, given advanced age and only having 10X annual spend. Hopefully I can find something better that I'm happy to work 5 days at again, though I don't need to hurry.
I've been unpleasantly caught between stress at home (child having pretty big problems) and stress at work, and something had to give. It'll be an adjustment, not having the net worth go up for a while, but I'm really grateful I can afford to do this. And that I know I can, which probably wouldn't have been the case before discovering MMM, Jim Collins etc a little over a year ago.
I can only imagine how satisfying the full FU must be!
