He deals primarily in the high risk/high gain market though. I think if you asked Mark he would say a business that lets you make just what you need -- a lifestyle business -- isn't a bad thing at all. The people that want to start a high risk business and raise money to help them swing for the fences should be prepared for some stress though. Those people are his audience. I don't think he meant that simply choosing a path of entrepreneurship means that everyone will have this experience.
You're probably right, but he should have chosen his words more carefully. It's very easy to misunderstand him and conclude that starting a business is inevitably going to be shitty.
