Just one million? About 6 months, as I currently earn over $2MM per year from my options alone at the company I work for thanks to their IPO. Once those dry up it's going to be a hard sell for me to stay. Maybe I'll coast for a year on cash + RSU salary (which is much less than salary plus pre-IPO options) to top off my $5MM investment portfolio and ensure enough of it is invested to produce an income, but after that? No thanks.
