At the outset of my career, fueled by confidence and theoretical knowledge, I believed I operated at the pinnacle of my abilities. However, as challenges intensified and my productivity waned, I realized the complexities of the job surpassed textbooks and training. Years of on-the-job learning exposed my knowledge gaps. Now, as a senior leader, I witness the Dunning-Kruger effect in newcomers and experienced professionals alike. Coaches and mentors play a vital role in guiding individuals toward self-awareness and continuous learning, ensuring they embrace humility alongside expertise.
