Maybe looking for something isn't very motivating because there's uncertainty about
whether you'll find it or not. You could try re-wording or re-thinking the action to
define it as "done" whether you find the ipad or not. Maybe "Look on top of 5 pieces of
furniture to find out whether ipad is there or not". That way you can check that
action off as "done" without spending an infinite amount of time searching,
which would be hard.
After that's done you can decide what the next action is: further searching in
the same room, searching in other rooms, buying a replacement ipad, or whatever.
