The amount of knowledge you have about a potential employer, and on the industry in which you hope to work can give you a competitive edge. This pertains both to making initial contact with employers and before going on interviews. In addition, having information on a company is also invaluable when it comes to evaluating a job offer.
After you've landed a new job, the excitement of starting something new may be accompanied by anxiety and guilt over leaving the familiar and perhaps some good friends, too. Even if you're leaving mostly enemies behind, it's still a good idea to leave your job in good standing.
In some respects building a successful career is no different from any other project. Clear goal setting, thorough planning and effective execution are key ingredients in the recipe for success. Though expert advice can help you with the process, in the end it is up to you to formulate objectives, develop a plan, and follow through to realize your career goals. While you may enjoy your share of luck, success seldom falls in your lap. Furthermore, if you ignore the basic principles of career management, an unexpected setback could badly damage your long-term prospects.
