Made Good Use of the Prioritization Scheme

I still have lots of stuff on my plate.  There were things I wanted to do, and things I needed to do.  I was a bit frustrated that I couldn't do it all.  I used the prioritization scheme and felt better about reducing something I wanted to do.  I did half of it, which was plenty and gave me more time to address the things I needed to do.   I'm liking the prioritization scheme a bit more.  I think the trick is to use it for guidance when making decisions.  It certainly doesn't cover all situations and doesn't need to.  Have you tried it?  Have you customized it?
