Sometimes it is completely unclear what skills it is to develop in yourself to excel in a career. Here are three questions, the answers to which will help to understand:
How critical to me and my career is the ability to communicate with people? How does my income depend on this?
Are there people in the company where I work, who are moving faster than I am? What can they do that I can not do?
How much does my ability to keep emotions under control influence my productivity?
Do not hurry and answer these questions in detail. You must determine what you need to focus on at this moment in your life.
