I used to be an IT Project Manager..To me, project management is a big fancy word and titles and certificates...for getting stuff done.
You know when you are planning a vacation and you have to plan 20 different things (from the airplane tix, to the schedule, to who's watching the cat, etc) and you have to make lists, and get them done in the right order, and coordinate with everyone. That's project management.
You'd be good at it and it's definitely a skill in need. But I agree...Certificates are great and help you with project management. But the best PMs I've met - just do it and learn on job.
