Playing Games at a young age have taught me...

  (Edited: )

A wise man once said, "Genius is eternal patience."  For a game like Starcraft, patience is an important element.  Not over committing, and to maintain your lead, as another wise man once said ;).  Besides patience, money and time management is also another thing games have taught me.  Another wise man once said, "The secret to winning is constant, consistent management."   Starcraft II being one of the best video games to teach them all, it encompasses multi-tasking, focus, and thinking on the ultimate level.

I can go on, but what have games taught you?
