Along with the boredom I'd image you have the anxiety of getting fired or laid off if someone realizes you don't actually do anything. Then when you go to get your next job you won't have anything to show for the last n years.
Well when your CEO is convinced you have product market fit when you dont, raise millions and burn it all in a few years thinking you can hire your way to a robust sales pipeline, it doesn't feel as bad.
Especially when the best sales ppl are leaving and you cant hire new fast enough so they stick with whatever they have, even if their book rate is at the bottom.
Basically sales teams are for selling but they cant sell products which have no demand and so eventually you are "that" company in the expo with nobody coming to the booths since your marketing involves using shady eastern European seo backlinks and believe repeatedly spamming CEOs and partners. In fact, when your partners turn on you, it's a sign that there is problems at the top level.
Usually these type of CEOs are egomaniacs with no discernable skill other than walking around the office taking up conference room to meditate, and thinking he is at TEDtalk...
