I am not a PM packrat. I only have 35. I have yet to have more than 60 at any one time. If it's a truly important PM, I copy it and save it to a file on my hard drive.
I'm the same with my e-mail. I have 6 e-mail address that all dump to one nice convenient place and still, I only have about 15 messages in it. I clean it out multiple times per day. I have a folder for things I need to keep.
Is it weird that I tolerate virtual clutter much less than physical clutter?
