There's a reason this Justin Kan quote has become famous to the point of being a meme:
"First time founders are obsessed with product.
Second time founders are obsessed with distribution."
You just learnt through bitter experience that distribution is the far harder problem to solve. You need to figure out who this thing is useful for, what is a way to get it in front of them and then how to adapt your product to get it to click.
I think there should be an addendum to that quote that "third time founders are obsessed with runway management and getting money for their products". Companies die because they run out of money and you ignore your balance sheet at your own peril.
This is an excellent point. You need to understand why your customers are buying your product, and make sure that's actually why you're actually trying to provide.
