When stomach is full,
everything mind does then is a search for something worthwhile to  do.
In most men this is thinking about the next meal;
the brain’s thought generating neurons, same as every other cell in the body,
are programmed for activities supportive of survival,
thus even when such is not the instant issue, brain’s thoughts instinctively drift to matters related thereto (food, physical safety, sex).
But thought (perhaps from the tedium of repetition)
has expanded the scope of its activities out from the mere essentials of survival
to elaborations and augmentations thereof.
What activity could be more fitting the human mind  --
the observable zenith of intelligence in the entire universe --
than its concern for survival,
and what less would you expect of it when not so involved
than to engage in pursuits of the highest caliber  --    but what?
What is comparable in quality to mental enterprises supportive of survival?  Nothing  --  so starting from the core of essential survival needs, mind has
spread out in all directions, experimenting and creating for itself  --  as it goes  –
things to think about which may prove worthy of its talent.

Simple historical observation shows this to be an on going affair --
an endless search-come-creation –
which has produced in toto, the worldwide realm of culture:
that facet of all men’s lives which they cannot touch with their hands  --
which originates entirely from their minds.
Humanity’s mental destiny is the brain’s ceaseless search for
something worthwhile to think about when not thinking about survival  --
and here  --   the certain man sharply parts company with the crowd.

Based on the past, the present, and the latter’s tips on tomorrow,
mankind’s fate is to look  for something worthwhile to think about,
and the certain man’s  --  to find it.
The realization is finding it;
DoingTheThing is the effort to keep pushing yourself beyond the place
everyone else is looking so that you can find it.
 
 

Those looking have given many fine and glorious names to their goal
(such as: God, Truth, Understanding)
each of which is intended to represent to some minds the epitome of
something worthwhile to think about,
but the names are of no substantial significance  --
the drive behind them is the key:
the hunger of the brain’s conscious operations to find something
worthwhile to think about
when it has nothing of instinctive, physical importance to think about.

Once the certain man’s vision is straight --  it is clear as can be
that every single facet of every cultural activity ever on this planet
was/is a manifestation of the brain’s endless search for something
worthwhile to think about;
when you realize it (figuratively speaking) you cannot believe that you did not do so long ago, or that other people cannot also  --  but they cannot:
they cannot be permitted to recognize that what fuels the constant running of their thoughts for 99% of their lives
is their mind’s search for something worthwhile to think about,
for if this occurred in an ordinary man, it would shut down or severely impede
the basic operations of routine consciousness.
 
 

Two possible states of consciousness:
the ordinary one with thoughts mindlessly meandering in search of
something worthwhile to think about, or: paying attention;
it is the difference between laying down and standing at attention;
it is a question of effort: the first requiring none, the second, constant,
