Catchy title with strong words ('57-page', 'YC'), no real click-bait but close.

I skimmed the first pages and most of the advice is neither wrong or bad. Still, reading a lenghty 57-note in order to learn is wrong.

You learn by doing. If you want to start something stop procrastinating on HN and execute the first step: found the legal entity for your endeavor. This will keep you busy for the next days, and you learn.

Btw, you don't need to have a good or any idea or co-founder now. This will all come. Just start, make mistakes, stop reading random advice.

Edit: Don't downvote if you disagree, downvote if a comment doesn't add anything to the discussion.
