What is your motivation to change jobs?

Are you getting tired of your job? Thinking about looking for a new employer? Then make sure you thoroughly analyze your feelings before making any decisions: What is bothering you exactly? What do you feel is missing in your current position? What are your strengths and weaknesses? ...

Perhaps you want to get promoted, but feel you lack certain skills needed to move on to a higher level. Talk to your employer and ask about classes or seminars you could attend to acquire new skills or improve the skills you have.

Another possibility is that you are so good at your job that your employer simply does not want you to move on to another position. Talk to your supervisor and check if your company is perhaps willing to create a new position for you, which allows you to use the skills you have, and develop new skills at the same time.
