Blake Shelton is shifting his priorities. The country music superstar, who is set to coach his final season of NBC’s The Voice, says he’s ready to focus on the personal aspects of his life. “I’ve accomplished more than anything I would ever imagine and made plenty of money, but you can’t buy time back. [Family] is what I want to invest in now,” Shelton, who is married to pop superstar Gwen Stefani, reasoned during an exclusive cover story with PEOPLE.
