William McRaven: There is this perception that — it’s not to say we in the special operations community don’t have a swagger. You have to have a swagger, you have to be confident. But when you sit down to do a mission, you have got to do the detail planning. You have to do the detail rehearsals. You have to be physically fit and mentally prepared. And that doesn’t happen by accident. That happens through very difficult training and appropriate preparation.  So anybody’s belief that you can go do a complicated special operation in a cavalier manner has never been in the business.  To be a really good special operator, you’ve got to care about the details.
