I'm really surprised by the number of people trying to solve the author's problems. I don't think he posted this because he didn't have any good ideas on how to hire someone or wanted copy help on his hiring page.
I think he posted it because sometimes the most helpful thing is knowing that you're not the only one who wakes in the middle of night thinking about payroll and customer acquisition. I think he's wondering if other people have doubts and struggles. And anyone trying to start a company right now would know that as soon as they read it.
So, yes Jason, this is how it's suppose to feel and it's okay that it sucks. Just remember, you're more important than your work.
