I wrote a response to this because I recently shut down my company, but when I was finished I realized that none of the advice was actionable, and I didn't know of a good framework for this.

I visited a lot of coworking spaces and met people working on things that had been doing so for years with no traction. Some of the people clearly didn't what problem they are trying to solve. Some really solid advice or a framework for when to know your business is toast would be an anti-sv culture thing, but could be extremely useful for helping people get their life back on track.
