It's better to look at it as a game and an experiment. If someone gets too in-love with their "baby," emotionally or identity/ego, then they won't be able to pivot, chop it up, exit, or strangle it.

Take a break, get a job, go on a coke bender, sleep with 3 affiliates of VCs, become a Twitch DJ, vlog from India, sell windmills, have a kid, whatever it takes to get back to making a living or trying to make livings. It can be difficult to unfuck your shit after a big loss, do whatever physical or emotional labor is necessary to get back to an even keel. Psychological and/or pharmacological assistance could be needed for some people.
