In Chapter 5 of 18 in his 2013 Capture Your Flag interview, entrepreneur and community builder Fabian Pfortmüller answers "How Are Your Aspirations Changing As Your Experience Grows?" Pfortmüller finds life in his 30s teaches him life is more a marathon than a sprint. As a self-described ambitious person, he finds ambition can be dangerous if you do not maintain some work-life balance. He creates more with doing less and, surrounded by ambitious peers, finds what is right for others is not always right for him. Rethinking career ambition helps Pfortmüller better balance professional and personal goals, including family and relationships. Fabian Pfortmüller is co-founder of Holstee, a socially conscious online marketplace, and Sandbox Network, a global community for young entrepreneurial people. Pfortmüller graduated from Columbia University.
