The best way to deal with a blank page (or blank screen) is to simply not have one. Asking how one deals with a blank page is a bit like asking how one deals with an Ed Hardy thumb ring or a pinstriped fedora. Just avoid that whole landmine by not ever having one. It helps to have a backlog of ideas -- more ideas that you could ever possibly need or turn into finished stories. I keep a text file of half-baked ideas to develop should I ever get some spare time -- and some of them aren't half-bad. Be riddled with ideas. Sodden with them. So many ideas that you start to gag just in describing how many ideas you have.
