Beyonce Knowles looks unbelievably fit and sexy in the February 2013 issue of GQ, where she discussed how her incredible work ethic has made her the person she is today.
"One of the reasons I connect to the Super Bowl is that I approach my shows like an athlete," Beyonce told GQ. "You know how they sit down and watch whoever they're going to play and study themselves? That's how I treat this.
"I watch my performances, and I wish I could just enjoy them, but I see the light that was late. I see, 'Oh God, that hair did not work.' Or 'I should never do that again.' I try to perfect myself. I want to grow, and I'm always eager for new information."
Knowles, who's preparing to perform at the Super Bowl on Feb. 3, lost 60 pounds a few months after giving birth to daughter Blue Ivy Carter by dieting strictly and working out rigorously.
"There are no secrets [to weight loss]. It takes discipline!" said Beyonce, who counted calories and worked out five days a week. "I've been working really hard. Be sensible and exercise constantly."
Beyonce's focus and discipline has driven her success her entire life. "I worked so hard during my childhood to meet this goal: By the time I was 30 years old, I could do what I want," she says. "I've reached that. I feel very fortunate to be in that position.
"But I've sacrificed a lot of things, and I've worked harder than probably anyone I know, at least in the music industry. So I just have to remind myself that I deserve it."
While becoming a mom has been extremely fulfilling, it made Beyonce realize just how important her work and career are to her.
"I love my job, but it's more than that: I need it," she says. "Because before I gave birth [when I didn't work], it was the only time in my life, all throughout my life, that I was lost."
Beyonce is well aware that she has a lot of influence on her fans, the entertainment industry, and on pop culture, and she owns it.
"I now know that, yes, I am powerful," she says. "I'm more powerful than my mind can even digest and understand."
