Just looking at employers in my professional career. Two. One for 15 years then the current for 3.
Looking at my direct and diagonal leaders, they seem to average 3-5 years a role, and I consider staying with my prior employer for so long a mistake. I made career progression and promotions there, but it still slowed me down vs changing employers.
I used to be in credit risk for a very large stock market company.
Calling the bottom of the market is the same as betting big and getting 21 in blackjack.
Super cool when it happens, but not skill. The number of grown men I had to hear crying because they were dollar cost averaging down to the bottom until they went broke still disturbs me.
I’m happy this worked for you, but it was not skill.
