Yep, your points 1-3 were exactly what I thought was going to be a waste of time as well. But what I have found about all good processes, they simply aren't magic. No business got made simply by watching videos or talking on the internet with some strangers.

I found SuS to be more like a framework or a guide for my own work, not an end result in itself. I applied what I learned, not expecting to get much for free, and it was invaluable for me.

Did you participate in ever group meeting? I took notes, asked the other people questions, and this was both instructive and encouraging. Did you watch every video? I did, and learned stuff from hardware businesses I never would have learned just watching videos on software focused discussions.

Most of all, almost everyone speaking really seemed to walk the talk, not just have good theories. The last video (that I recall) was about health, physical and mental, and it was enlightening.

I hope you consider trying again, and look at it from a different perspective.

Yep, they like their unicorns, and I suspect my business will never get funding, but that's not why I participate, it's useful for me to change my perspective. Maybe take on some of the traits of highly successful businesses and apply it to my own.
