Hwang Min Hyun said, "I started dreaming of becoming a celebrity in middle school" and added, "Appearing on an audition program was desperateness itself. We wanted to become Wanna One so bad that I practiced while only sleeping 1 hour (per day) during the 6 months."

Next, Ong Seung Wu said, "It's been 10 years since I started dreaming of becoming a celebrity. I've worked hard and also played hard before. Out of all, I think confidence and self-esteem are the most important. Of course, there were times when I felt discouraged and ashamed but I had hope thinking, 'I'll succeed. I'll do big'."

Kim Jae Hwan also said, "During college, I really wanted to sing but it wasn't easy. I had to work part-time. I worked hard and with the money I made, I rented a practice room and practiced."
