Hilary Duff's approach to self-love is what dreams are made of. "When everyone in my household is happy, that's when I feel the most confident," the How I Met Your Father star told in an interview while promoting her partnership with supplement brand OLLY. "And, to be honest, I love what I do and that's a huge boost, to be feeling confident in the workspace, but also, when my whole household is thriving, that makes me feel great. You feel Superwoman powers when everyone's had a great day." While striking that balance between her home life and professional commitments takes "a lot of work," Duff said, her evolved approach to fitness has helped her maintain a routine. "You have to make it a priority for yourself and your health," the 36-year-old explained. "I had to change my mindset around it and not be like, 'This is for me to look good.' I have to be like, 'No, this is for me to be good inside for my family.' It's not just about what's on the outside, it's about what's happening to your brain."
