James Altucher, an entrepreneur, writer and host of "The James Altucher Show" podcast, is a master of reinvention, so much in fact that the title of one of his 18 books is "Reinvent Yourself." Altucher has built and sold numerous companies (and made and lost a few fortunes in the process), once gave up all of his possessions and was homeless for a time, dabbles in stand-up comedy, and all the while has maintained his long history with meditation.
