BBC News examines the growing trend for people to change their career.
Are you bored of your job?
Are you itching for a promotion, a better job title or just a change of pace?
If so, think about what's missing from your present job. Is it too stressful, too challenging or too monotonous?
Do you need something different? Slower paced, more exciting or more creative?
Is it your boss or a member of your team that you can no longer work with? What would you like in your next employer or colleagues? If you made mistakes in your working relationships, learn from them and make sure it doesn't happen again.
Before you move on, think about whether you are making the most of your present job. It may be the wrong job for you - but equally you may have become set in your ways or stopped being proactive, which has resulted in the work becoming dull and unrewarding.
If this is the case, is there anything you can do to remedy this? If not, learn the lessons so that your new job will be all that you want.
Most jobs have a natural lifespan and time will come when you will have learnt all it has to offer. This often happens with a first or second job, but can strike at any time in your working life - it's easy to get stuck in a rut.
Make more of your job
Take on new projects
Offer to help in a different department
Take advantage of training opportunities
Go for promotion
But if you find yourself moaning to your friends over a pint on a regular basis, your present job could be on its last legs and it's time to get back into the job market.
One final tip - try to get another job before you leave your present one. It may sound obvious but many people decide that they can't bear their present job and bail out overnight, leaving themselves cash poor and insecure.
The old saying that it's easier to get a job when you have a job is completely true, so don't do it!
