I've accelerated my net worth by a rate of return of 12% compounded over the last 20 years of professional life. My resume has 10 separate entries in it which means I last on average two years.
Why do I expire after two years? Because no one in my industry gets promoted from within. No one in my industry is ever given more than a cost of living wage increase, and certainly not a 12% year over year average increase. It takes two years of watching people get hired over you with no raise to decide that you deserve more money and you go out and find it.
I believe in judging my value in monetary terms and as I increase my experience, knowledge, and value, I expect that amount to increase as well.
