The older she gets, the less Duff is concerned about what the future has in store—particularly with her 30th birthday approaching this September. "I think I'm a pretty confident person. I've had a career for a long time, but I've put a lot of unnecessary pressure on myself as a woman, a businessperson, an actress. I'm like, 'Am I doing enough?' Everyone I've talked to says you come into your own in your 30s," the singer says. "You feel more secure. I'm looking forward to that."
