What do you want to know? I have my PMP, I design and teach a PMP exam prep course at a college in my spare time, and consulted in Project Management, worked a PMO, in my real job.
Some random thoughts for this thread.
My PMP has helped me, but more in the way credibility, and with employers, they know I can hit the ground running. Also, I wouldn't be able to teach the PMP or project management without it, but that's not why I got it.
In terms of experience hours, document it as if you will be audited. They have been targeting 10+ % for audits. Keep it focused on the Project management speak.
It's a tough exam, it will get tougher at the end of their end year when the exam changes for the new PMBOK6. If you are planning to write it this year, you should make up your mind now, or decide to wait u till the new changes have settled.
