You shouldn’t start any small company if you are already an executive president. That’s hustling backwards, instead just sit on boards of big companies.
I don't disagree with you.
I'm just saying that if you really wanted to get your rocks off with "being your own boss", that option is available.
There is no reason to pick owning a small company over securing a position that will earn you 10s, maybe even 100s, of millions.
