Baduk teaches you that cramming before a match doesn't really work.

In order to be a strong player, you need both logical and emotional approach to solve problems in actual games.

Unlike many other games today, baduk is a long-term oriented game; one game easily involves a couple hundred moves, and you cannot cram your study in days or weeks.

Think Global, Act Local. Indeed true in baduk, as well as in international business! 

At first it's easy to feel attached to a game or particular stones on a board as if losing them would be an end of your life.  Again and again, however, you learn that what you lose is not yourself, and you can always start fresh from the beginning.
