I have 1) Evernote GTD to do's (they are in my computer, not printed) 2) physical to do's (actionable items that are printed on a paper) in the drawer. 1) and 2) should be in sync all the time? or is it ok, some of the files, todo is in just computer (Evernote) and some of them in the drawer (printed)? as I get some of the reference files will be both in computer & physically existent; some of the reference files will be only physically existent in the drawer right? each paper that exists in the drawer, should be in my computer, Evernote, right? how do you manage it?
