You Can Play Go But Don't Let Go Play You
Don't be passive when playing Go. It's not fun and not good for the brain. A pro said play the move you want to play. So every stone that you place on the board must be a sincere expression of your ideas.
 The pro was Takemiya: see, for example, http://www.usgo.org/congress/2008/ej/2008.08.07%20V9%2040%20AGeJournal.pdf
Or don't: the link's broken. Can anyone fix it?
