Intelligence is a mosaic and as such precludes specialization.
The set of skills that define a particular human being are like a hand of cards that have been dealt to the individual by the universe. It is imperative that a warrior explore every avenue to determine if there exists a skill there that may be added into the rest of his or her mosaic.
If you have your feet on the ground
And your head in the clouds with God,
that makes you very tall.
