I happen to agree quite a bit with the OP. As revenue from my startup grows, I see it as buying time back from consulting. This year it will buy about 3 months. Maybe next year it will be 6. Eventually I hope it to be 12+.
I'll never get rich, but eventually I'll be free to work solely on my startup without anyone else telling me what to do. No one will envy my car, but many will envy my lifestyle.
