Colin Marshall sits down in San Francisco's South Beach with entrepreneur, author, blogger, traveler, and learner Ben Casnocha. His latest book, co-written with Reid Hoffman, chairman of LinkedIn, is The Start-Up of You. They discuss the advantages of hanging an IKEA world map on the wall; his ten days of silent meditation and the feeling of enlarged thumbs that resulted; the San Francisco Bay Area's convergence of Californian spirituality and Californian technological intensity; the three Californias: San Francisco, Los Angeles, and everything else; "NorCal" pride and State of Jefferson stickers; being the average of the five people you spend the most time with, and how that got him involved in technology startups to begin with; how where you physically live now matters both more and less than it used to (and who still lives virtually on Livejournal); how loyalty now extends horizontally to your network rather than vertically to your company, and how your identity now comes before your role as an organizational component; his lifelong habit of reaching out to interesting people, and how it differs from the standard sleaziness of "networking"; his visits to Detroit and Athens, and how those cities may have strained his appreciative thinking muscles; his interest in underrated and underdiscussed places as well as people, such as those in South America; his adoption of "home bases" around the world, be they in San Francisco, Santiago, Zurich, or Tokyo; the pronunciation of Tegucigalpa; the loneliness he sees deep in the eyes of people who declare themselves "nomadic"; the necessity of acting consistently on curiosity, and of cultivating both a highly technical and a highly nontechnical mind; whether moving to a city means moving to randomness; and his sensory-deprivation experience floating in a saltwater pod.
