4. Thinking You Have Nothing Left To Learn

Bill Gates has already warned against the rot that sets in the minute you believe you have no growing left to do. Thinking you know everything is a guaranteed recipe for you to become irrelevant and outdated because you stop striving to improve yourself and your work. Nobody is (or should be) done learning; that includes you. Reading, conversing with people, and taking every chance to upskill; all of these contribute to growth; the skill most necessary for professional success.
