I have a superstition that when people in a startup start fabulating about the company jet it's time to jump ship. Based on a sample-of-one experience, but I've happily extrapolated to the population (statistical word meaning). Since I'm with another startup I hastily and aggressively stop anyone talking about possible riches as soon as they try to voice such thoughts, to prevent the curse from spreading.

I know I can make plenty of money with established enterprises - have done that as employee and as freelancer, getting lots of money. So I'm at the position I'm in, while giving up a lot of sure and easy money, because I hate 9-5 jobs and doing highly paid but uninteresting projects (and not infrequently I got paid for nothing but being present, even when they had to pay an hourly rate). I don't want coworkers with dollar signs in their eyes.
