This article highlights the differences between amateurs and professionals in various aspects such as goal-setting, feedback, consistency, failure, knowledge, decision-making, and focus. Professionals understand that achieving something is just the beginning and focus on the long term. They seek out thoughtful criticism, accept responsibility, and make decisions as individuals. They also focus on their strengths and finding people who are strong where they are weak. Amateurs, on the other hand, stop when they achieve something, think they are good at everything, and blame others for their failures.
