I've only started to re-use PR ... I'd say that I'm at the 'Conscious Incompetance' stage. I have the tools to do the job, but have not completely mastered the job yet!
I notice I am not as confused in regards to what needs to be done to perform PR. I am more relaxed. I can photofocus more efficiently. Its' just a matter of time before the entire process 'gels'.
I also make it a point to regularly visit this DB board and participate and ask questions ... this in inself will help 'newbies' like myself to gain the necessary confidence and know-how to become a master of PR ...
