I'd like to add realistic departure opportunities if you get tired of the job: BigCo: No sweat, I'll get another job by name dropping BigCo and its people who are likely also well known. StartUp: I can never leave, too many customers rely on me, I have too much riding on this. SmallCo: Notice of intent to leave + maybe a month or two to find/train the next human.
