In this episode, Dr. Killeen shares a candid reflection about the different kinds of motivation that drive success. He talks about "dirty fuel" and "clean fuel." Dirty fuel comes from trying to prove people wrong or chasing external validation. It can create incredible momentum and push you through difficult seasons, but it often burns hot and fast. Clean fuel comes from purpose, values, and the desire to build something meaningful for your family, team, and future. Both types of motivation can play a role in growth, but long term fulfillment usually comes from shifting toward the cleaner source. Pause and ask what is truly fueling your ambition right now.
