Recently, I saw Dr. Christine Darden, a woman who began her 40-year career as a NASA engineer in the 1960s, speak at a Woman Up event. Dr. Darden broke through barriers one afternoon when she decided to take a risk and speak up… even if it felt uncomfortable and scary. By asking her superior a single question, she propelled herself forward to where she wanted to be. See what lessons we can learn from Dr. Darden about asking the right questions, breaking through social constraints for women and why we shouldn't give up on dreams.
