You wake up and roll out of bed.  You strap on the rare gauntlets you found yesterday, you realize you don't have time for breakfast.  When you reach the mouth of the cave, you load your rifle and pull the trigger.  The thrall's head snaps back, it's body crumples to the ground, and you try to decide whether you hate this daily grind or whether it's the best thing in the world.  This week, we revisit the concept of "grinding" in games.  Whether it's farming rare items or trying to trying to level up, what lessons can we learn from devoting time to repetitive action?  As always, jump into the comments and share stories from your time in the mines.
