Joan Lunden and I took some time to chat about aging (I confessed my fears of 50 to her) and how to overcome self-doubt and instead embrace your self-confidence. You may know Joan Lunden as a former co-host on Good Morning America for nearly two decades, making her the longest running female host ever on early morning television. But it’s how Joan continued to be fearless after GMA that stands that makes her such a rockstar to me.
