Go over in one's mind.
Back up and go over.
Make arrangements in the mind.
Back up and correct.
Take not of
the wonders of a computerized mind  -
I'm just being facetious there, and
for that matter the wonders
of a schizoid mind - I'm just
being facetious again.
The best I can do
for my own thing
is counting sheep
and I, of course
got that off of others.
