I'm attacking the idea that anyone can start a successful startup with 10 hours a week - not the idea that anyone can start a successful startup (although I'd say even there there's a bar, but it's much lower).
DHH, in this article, presents a method that he suggest applies to anybody. I'm just saying it doesn't apply to anybody.
If you weren't working in 1996 (unless you graduated early, you were in high school, swombat) I'll say: do not underestimate how silly things were back then.
The book "Growing a Business", written in the '80ies, about a gardening catalog company of all things, has a lot of the same lessons as "getting real", and to boot comes with its very own ISBN.
Here's my summary of it (but go buy it, it's a good one):
But this looks like an awesome book, and I just bought it. Thanks!
"Odds are you’ll fail. Just as odds are you’ll fail if you take millions of VC money, hire a staff of twenty, and spend 120 hours/week on it."
The take-home point of the essay, ISTM, is that if you only have 10 hours a week for your startup, those 10 hours can still be well spent.
