In speaking with four Stevens alumni pursuing fascinating and diverse careers, we asked them to share their stories of illumination that guided them toward deeply meaningful work. A recurring theme emerged: Each could pinpoint a turning point that offered a chance to make a positive impact on the world — a realization that this was their calling. Their reflections are deeply personal, filled with firsthand accounts of challenges, triumphs and self-discovery.

Following are excerpts from these conversations — plus some insights related to pursuing a meaningful career — edited slightly for length and flow.
