But if it's procrastination because I'm trying to avoid it (because I'm not good at it), isn't that the perfect opportunity to bring in the "marketing guy/gal" cofounder to do that work for me? Ideally, you would then only have to actively "sell" it to one person who can pass it on to the rest.
What's being called procrastination here, I'd prefer to call specialization. But I'm probably being naive about this.
