Major life transitions such as leaving the protected environment of school or starting a new career can be daunting. It is scary to face a wall of choices, knowing that no one is going to tell us whether or not we are making the right decision. There is no clearly delineated path or recipe for success. Even figuring out how and where to start can be a challenge. That is, until now. As executive director of the Stanford Technology Ventures Program, Tina Seelig guides her students as they make the difficult transition from the academic environment to the professional world, providing tangible skills and insights that will last a lifetime. Seelig is an entrepreneur, neuroscientist, and popular teacher, and in What I Wish I Knew When I Was 20 she shares with us what she offers her students—provocative stories, inspiring advice, and a big dose of humility and humor. Tina Seelighas a Ph.D. in neuroscience from the Stanford School of Medicine and is the executive director of the Stanford Technology Ventures Program, which is the entrepreneurship center at Stanford University's School of Engineering. In addition, Seelig teaches courses on entrepreneurship and innovation in the Department of Management Science and Engineering and in the Hasso Plattner Institute of Design at Stanford University.
