I haven't taken a break but sometimes I need a kick in the butt to stop reading and get scrapping
I like to dive in with something that excites me: kit, photos, template, challenge... something that makes my heart sing.
Maybe if you have a big backlog, make a list of what you want to scrap and then look and see if anything special jumps out? (Ex: When we got back from a trip to Kennedy Space Center, the first thing I did was the Shuttle Launch Simulator. It wasn't the first thing we did but I wanted to use a specific template and kit and was ready to go!)
