I've yet to see a company that, having sound leadership, failed. I've also never seen one to succeed with bad leaders. And the surprise is that being a “good” or “bad” leader has nothing to do with how you treat people around you. You can be a tyrant (Steve Jobs), a bully (Bill Gates), a corsair (Larry Ellisson) or a friendly, passionate geek (Larry Page, Sergey Brin) and succeed nonetheless. But if you lead in the wrong direction, then boy, you'll hit an iceberg sooner than you can spell “Titanic”.
