When I see or hear advice, I try to understand what the person's context was. Here, I feel like I don't know enough about the founder's situation to know whether any of this would be relevant to me. For example, does he have a family? How old is he? Roughly how much money did he sell for? How much profit was the business generating beforehand, and what was its trajectory?

Without knowing things like this, I can't really tell if his advice would be relevant at all for me.
