Aptitude
is NOT about ability. 
It is nothing more... ...or less, than 
Repeated task.
With any and every known human task,
the outcome is directly related to the mental input.
 This outstrips even the most heroic physical effort, because the soul precedes the body in every journey. 
  This becomes a powerful, fast-acting tool with nothing more than mental focus upon it.
You could do much worse than investing a minute or three considering this.
At the core of it all,
Attitude
supercedes
Aptitude
in determining
Altitude
Be good enough to remember
 that there is no coincidence to the fact that
 the winner of every race is also the hungriest person
