Leadership is very rarely about doing what's easy. If the decision ends up on your desk it typically means no one else can or should be making it. As Harry Truman was fond of saying, "the buck stops here." If you are delegating properly, then your people will feel empowered to step up and make most day to day decisions. If you are picking the right people, then they will be capable of using sound judgment and thinking through just about anything. However, some issues still do come down to leadership prerogative and accountability.
