As you advance in a company, success becomes less about the specific work you do and more about who you are as a person and a leader. It’s about your ability to create broad visibility, credibility, connections, and support outside your organization. The higher you go, the more your results come from enabling people who work for you to deliver great things and from working with people around and above you to eliminate obstacles, get ideas, negotiate for resources, secure cooperation, and build momentum on a large scale. It’s not about the work you deliver personally.
