In 2005, fresh into his first banking job at Citigroup, Tom Bock found himself working 63 hours straight to prepare for a critical pitch. Fueled by a desire to prove his worth, he pushed his limits, refusing to rest until the task was completed. However, this grueling experience came at a cost—his nose began bleeding, a stark sign of physical exhaustion. Despite his best efforts, the pitch fell short, leading Bock to a moment of deep reflection.At the time, Bock was someone who believed in sheer perseverance, equating success with pushing through challenges alone. But the Citigroup experience became a turning point in his career. Through discussions with mentors and careful self-assessment, he recognized the flaws in his approach. Bock learned three crucial lessons: the importance of breaking down complex tasks into manageable parts, the necessity of self-care, and the value of seeking help when needed.This experience broadened his understanding of success in finance. It wasn’t just about individual heroics but about effective teamwork and sustainable work practices. As Bock transitioned into more senior roles, these lessons became foundational to his mindset as a CFO. They guided him in balancing the demands of leadership with the realities of human limitations, ultimately shaping his approach to managing teams and making strategic decisions. Today, as CFO of Smart Financial, Bock applies these insights to ensure long-term success, both for himself and his organization.
