Is project management a worthwhile skill to learn?

My opinion here is it depends on whether you are going to become a team manager for big projects or not.  If your team is just working on smaller projects for small businesses, maybe developing a website, or setting up a network for the business, you would only need some basic knowledge and skill in directing a small team through a series of jobs.  On the other hand, if the project was something big, like developing and programming software for a big company that will be widely used, or undertaking a big restoration task for an old building, then this is an extreme case where you will need expert skills to be able to do the job efficiently and effectively.
