We all know entrepreneurship entails huge risks. However, that's no reason to not forge ahead. Most people can't seem to understand that entrepreneurship is not about money, fame or power. Those are all secondary things. Entrepreneurship is about an idea and its development. It's about developing a thought, a concept only you and maybe the 2 other people starting the venture with you understand. It takes balls and passion. It takes courage. But more importantly, it takes unrelenting love. Love for the idea behind the venture, love for the concept of creating something valuable out of just abstractions, and, ultimately, love for the better world you're helping shape with the economic impact of your plan.
I'm not downplaying the importance of following sound economic principles (e.g. do NOT put your house as a collateral for a loan). Nonetheless, if you're going to be deterred by the economy, your wife, this article, or a friend, then you clearly don't have, and probably never had, what it takes.
