I wish I'd see advice where they prioritize having a roadmap, milestones, an actual plan of execution, after Product Market Fit (PMF) has been found. And before you find PMF, any concern for hiring the 'best engineers', building a 'solid foundation' is moot.

I feel I'm going insane expecting product people to put the time in to define the requirements and context; I get weird looks asking startups about the plan for the next week. "That's how startups do it" is just the most bullshit excuse I keep hearing constantly regarding lack of planning.
