Nobody is a natural-born project manager. Such kind of knowledge always comes from experience. Start working on the projects at the low-end. For years. Work hard, understand the logic of the systems, learn more and more. All the time. Learn how the companies are working. Learn the different behaviours, motivations and reactions of the people. Start accepting more and more responsibilities in the projects. Try doing your best to complete your tasks, but do not hide if you fail. Sometimes you will fail. Learn from your mistakes. Stay calm and always positive. That’s all the magic.
