Reese points out that it is important to realize how great you are. "I've said this to Oprah before, but LeBron James doesn't go, 'I'm kinda sorta good at basketball.' He's like, 'I'm the best there ever was.' So, yes, I do think I'm very good at what I do. I've been doing it for 30 years. I know what I'm doing. Give me the ball."

Compared to men, Reese believes another crucial quality that females bestow is the ability to be humble. "Another important difference is that women have humility. I have no problem saying to people, 'I don't understand what you're saying, can you please explain it to me?' Self-doubt is a good tool. You shouldn't know everything. Turn to somebody, but advocate to learn more and do better," she said. 

Reese finds ways to feel young, including being compared to her daughter. "Well, I love being mistaken for her because it makes me feel so young. I'm so proud of her. She really rolls with it. I'm sure it's not easy looking exactly like your mother," she said. 

Reese's secret to looking good? "In my 30s, I learned to accept my body for what it is. This is what looks good on it. It will never look good in that thing over there with all the fabric and the bows and the ruffles. It just won't," she explained.

As she has gotten older, Reese prioritizes spending more time with people she loves. "I'm 45. I know who I want to spend time with and who I don't. And that is one of the great things about getting older — it just clears out so much space. I want to be with my mom, my kids, and the people who fill my tank. And everybody else, I wish them well," she says.
