I can confidently vouch for the person being a he.
I would attribute my net worth to “dumb luck” rather than skill or overall stock market return: had I known about investing I would have gotten rid of the Hoolie shares (for diversification reasons) the moment they vested (or the first day the blackout window* ended or would have later opted for the automated selling when that was introduced for Hoolies in Switzerland.
For the longest time, however, I looked at those Hoolie shares as “something extra maybe some day” tucked away. I wouldn’t even really look at them for years and only sell some to cover taxes.
Once I started to become interested in investing and later FI I realized that I had probably 95% of my net worth (outside pillar 2 and 3a) in those Hoolie shares and that I should perhaps diversify.
So the “dumb luck” of concentrating in and holding onto most of my Hoolie shares from 2005 to close to 2020 made sure I fully benefitted from Hoolie’s meteoric rise over that period (easily outperforming the S&P 500).
By the way, had I stayed “dumb” lucky" all the way through to today by not, ahem, … diworsifying away from Hoolie shares, I’d probably have joined the eight figures club. ¯\_(ツ)_/¯
Fun fact: I initially took a pay cut going from about 140k to 120k in order to work for Hoolie in 2005 …
It’s only after maybe 2010 when salaries started ballooning (out of proportion, IMO [but I won’t complain 
]).
