There are a lot of things to consider when deciding when and why to move on. To begin with, you need to assess where you are now, what you have achieved and where you want to be in a few years time.

What do you enjoy about your present job? What don’t you enjoy? What do you feel is missing? What have you enjoyed about any previous roles you have done? What is the ideal situation for you? How will you know when you have achieved it? What obstacles are in your way? What can you do to overcome them?

Try to be systematic in answering these questions. Discuss them with friends, family or a professional career change expert and write them down. It’s always easier to make an accurate assessment of a situation if it’s clearly staring back at you from a piece of paper.
