This week I'm interviewing Patrick McGinnis, the only other person I've ever met who broke the Myers-Briggs scale for extroversion. He's got some great tips on finding stories and integrating your book with your website, as well as some fascinating insights into the thinking behind his new work, The 10% Entrepreneur. In a world where no job is risk-free, this is a guide to carving out a portfolio life: balancing the security of the day job with the upside and fun of entrepreneurship.
