ELON MUSK: "The most difficult choice I faced in life was in 2008." "I think I had maybe $30 or $40 million left… I had two choices: I could put it all into one company, and then the other company would definitely die, or split it between the two companies. But if I split it between the two companies, then both might die." "I couldn't bring myself to do it, so I split the money between the two. Fortunately, thank goodness they both came through."
