I get this question very often, so let me explain the answer to it underneath.
For the past 13 to 14 years I have worked as a freelance project manager at a lot of nice companies. These were companies that are mainly in the media branch but also some semi-government companies as well as publishers.
One day you will be on a project team. Your manager has came up with a great idea, or maybe it was the CEO or that overzealous colleague from the marketing department. An app had to be launched, a new website or maybe a campaign for a new product to be released next month. A project team was formed, a kick-off was held and the chief in person came out of his office with a bottle of champagne to celebrate the happy kick-off.
