Browsing the Bogleheads forum, my eyes naturally gravitated to the thread titled “What is FI if you love your job?”
The short answer is that FI is financial independence. Nothing more, nothing less, and it doesn’t look any different if you love, hate, or feel indifferent towards your job.
If you love what you do for a living, but aren’t in love with the particular job you’ve got, you can explore ways to do that work in a different manner.
Rather than slamming on the brakes to bring your career to a screeching halt, it might make more sense to downshift and continue your work at a more relaxed pace.
You spent decades building a practice. It’s not like you can turn off the lights and leave your patients and staff in the lurch.
The easiest way to fight that feeling is to keep working until you’ve identified another purpose you would rather serve that might give you more freedom.
