Reflecting on how he's evolved as a person, Bieber attributes much of the positive change in his life to Hailey. "I just wanna be the best of me," he belts. "Even though sometimes I forget to breathe / So that I can be the best for you / That's all I wanna do." Bieber has echoed this sentiment a handful of times before. In a lengthy September Instagram post, he opened up about how marriage has made an important impact on him. "You learn patience, trust, commitment, kindness, humility and all of the things it looks like to be a good man," he wrote.
