After reading the following list, you should strive to develop as many of these qualities and tools as possible, and for those areas in which you are lacking, whether in experience, personality, or team resources, you should seek ways to compensate.
For example, if you are assigned to manage a project, yet are not an organized person, you should create a situation that will help you to execute the project in an orderly way, such as using a software application or recruiting the assistance of an organized member of your project team. When leadership skills are lacking, seek leadership development training or education. In terms of infrastructure, there are many free and low-cost tools available designed to assist project management, communication, and collaboration.
In short, now that you are aware of what is most critical to the success of a project manager, your goal is to enhance the management and/or leadership strengths you already possess, build yourself and your situation up where ever you can, and get assistance in those areas where you are still lacking.
