The old rules of work have changed. No longer must we stick to one lane for 35 or 40 years before earning a gold watch and a pension and really diving into our passions in retirement. James Altucher is proof that reinventions are more possible than ever. He has lived through four professional rebirths, along the way constructing a multi-faceted persona of entrepreneur, investor, best-selling author and podcaster. In this interview with Kindra Hall, he examines just how quickly we can bust through the notion of mastery. It's the subject of his latest book, Skip the Line: The 10,000 Experiments Rule and Other Surprising Advice for Reaching Your Goals, available everywhere Feb. 23.
