be it n little numbers attached to n specific letters. be it n little numbers enclosed in <>'s and separated by (n-1) ,'s. those n little numbers are yours. n belonging to positive integers.
now every moment changes from 1 to n of those little numbers in one of infinately many ways, each. life defined in n dimensions is much more complicated than point A to point B. imagine the error resulting in a linear approximation of a three dimensional object. multiply that by infinity. add the definite possibility of undefined external contraints, and you have one hell of a confused individual attempting to grasp the concept of "planning ahead."
