Had enough FU money to say FU!!
My job over the last 1.5 years was relentless and at times, unbearable. I just gave notice and will start a much lower paying job that should be enjoyable and give me time in my life to reintroduce all the fun things I enjoy doing (e.g., softball, pottery, band) that I've given up. Also, the dog will get walked more frequently and my spouse will actually see me! Other bonuses: shorter commute, and I can take the bus for free during the academic year.
I don't have enough to be financially independent yet, but I'm able to downsize jobs, save less each year, and still hit FIRE on schedule in Feb 2021.
I'm still finishing out my current gig, but I can breathe a bit better already!
(I'll need support when I'm not saving as much -- I'm an awesome saver and not being able to do so at the level I have the last few years will be rough!)
