In Texas, the Roadtrippers head to the Texas Instruments headquarters to meet Process Integration Engineer Byron Williams. Byron shares his struggle with self-doubt that almost stopped him from pursuing a career in science, and encourages the Roadtrippers to re-frame challenge as a motivator. Later, the crew heads to the ATT Foundry to speak with Senior Marketing Manager Tracy Parrish. Tracy discusses her switch from engineering to teaching, and helps Megan overcome her anxiety about teaching STEM subjects. The team ends the week at the National Space Biomedical Research Facility in Houston. There, Deputy Chief Scientist Dorit Donoviel discusses the courage it took to leave a comfortable job and try a new field. She encourages the team to never be afraid of venturing in new directions if they start to feel stagnant.
