a. stop doing what might be leading to the blockage (e.g. pushing stale food down the drain, smoking, or trying to think too hard to write for writing’s sake)
b. fix it (e.g. pour acid down the drain, get to jogging/exercises while you still can, get away from the net for a while into the real world outside… pick up a book (but don’t read it as if you are reviewing it… better still pick up an Enid Blyton… or Agatha Christie :), or paint sth (if you like to), or just go for some sun-bathing (if you don’t take the regular water ones :)
c. let the urge come back (e.g. urge to start pushing food down the drain, urge to light up that ONE stick, urge to write something that is not the same as trying to broadcast to a large audience :))

you get the picture…. !!

i’m positive, i’m blocked for sure now (from posting comments on your blog :)
