Last Tuesday, Jeff Bezos, the richest person in the world, said he’s ready to step down from his title as chief executive officer. Bezos said in a company blog post, “As much as I still tap dance into the office, I’m excited about this transition. Millions of customers depend on us for our services, and more than a million employees depend on us for their livelihoods. Being the CEO of Amazon is a deep responsibility, and it’s consuming. When you have a responsibility like that, it’s hard to put attention on anything else.”
