I leave you with one more practical and tactical tip. I call it the Shopping Center Test. Suppose you’re at a shopping center and you see someone you’re considering as your co-founder, but he or she has not yet seen you. You have choices: rush over to say hello, depend on serendipity to come face-to-face, or got to another store.
If you’re strong initial reaction isn’t to dash over to the person, do not make him or her your co-founder. This is the second most important relationship you’ll ever make in your life — maybe the most important, in fact. So go slow, do it right, and hopefully do it once.
