Ask HN: What's your biggest "no one tells you this" lesson from a startup?

[blinkbat]

"we're a move-fast-and-break-things, startup-paced culture" = you will be given no direction, mentorship, or goodwill, and our model is to squeeze you for development until you're bone-dry and then discard you. (you can tell I don't have a favorable attitude towards the term "startup".)
