Sometimes I find if I say I'm going to clean for an hour (like when I've been re-organizing my basement since last Oct) before I know it 2-3 hours have past, but I've got a lot accomplished. Just start with what's in front of you and take it one step at a time. Sometimes going to IKEA or someplace similar might give you ideas on organization too. I'm still working on my basement, but it's almost there as my new library and craft corner. Good luck! I'm sure it will be fantastic when you're done - and well worth the work!
