I have been reading "The Millionaire Next Door" as the first homework assignment from Dr. Bernstein's "If You Can". Together with my late wife, our whole working careers would qualify us as "prodigious accumulators of wealth", though we thought we were just being reasonably frugal.
I had a full tuition scholarship for college. My parents covered my room and board. I graduated from college with a small negative net worth (one credit card) and have been financially independent ever since, including a scholarship for MD-PhD training. I have not and will not receive any inheritance from my parents. I did inherit my late wife's retirement accounts (we both prioritized maxing out our available tax-deferred retirement accounts) and a small life insurance payout.
Total net worth, ~$3,000,000, house paid off
Retirement goal: ~$5,000,000 in current dollars
Pre-retirement goal: start developing alternative revenue streams that will enable me to cease working as a pathologist without needing to start spending down my stash
Best part is I now work 0.75 FTE, meaning that I have one week completely away from work in every 4 weeks. This could possibly be considered a phased retirement, as I now want to work even less, maybe move to 0.5 FTE as soon as my youngest graduates.
I use this down time to develop side gigs for life after medicine. Ultimately I would like to start and own a business (TBD) that is completely outside of medicine, but in the meantime I help develop content for CME and review content for other medical information programs. My goal is to find ways to be productively engaged (and compensated), no matter where I happen to be traveling on any given day of my upcoming retirement!
