You raise an interesting issue. Whenever you do something, you should ask, "Am I doing this for my customer or for my investor?" The answer may surprise you.
I bet both your customer and your investor would prefer if you focused all of you attention on your customer.
I am making an effort now to keep asking myself the hard questions.
I wrote exponentially worse and worse code as the hours
went on and then pushed right as I left for the “real
life” component. None of that code ended up working.
I'm all for crunch time pushing myself, but I learned the hard way back in college that all-nighters weren't very productive.
Does your boss ask you to pull all-nighters? If so, that's not very bright of him.
But it didn't take too long to start feeling the pressure from everyone to put in crazy hours like he is.. even if he's the sole owner and no one else but him will profit from it directly.
Said another way: the earlier you recognize the problems the better, best if done before you "fail".

Once you have a good Mentor, he or she can help you to avoid the other 4 problems in your list.
Find a Mentor who has a track record of success who can articulate how she achieved her success and learned from her failures. Buy that Mentor lunch every week or so, and get her thoughts on your pivots, the hours you're working, and your whole business model.
Informally commit to some goals in front of the Mentor and stick with them. If you get some other ideas like you want to pivot on your product, change your sales strategy, or dramatically alter your work schedule; try to satisfy your need to change by writing down the changes you're thinking about and then putting them aside to get back to the goals you set with your Mentor. At your next Mentor lunch, bring up the change ideas and get her feedback before deciding on your next short-term goals.
I'm not saying to let someone run your business or rule your life. All I'm suggesting is that you increase the speed that you're learning how to succeed by capitalizing on the successes and failure of someone else.
Like the saying goes, "A fool learns from his mistakes, but a truly wise man learns from the mistakes of others."
