Have you ever set out to meet a challenging and clear goal that has a specific end point? I know I have. Turns out I may be on a quest, which sounds a lot more exciting than "crazy hobby".
In his book The Happiness of Pursuit Chris Guillebeau not only defines modern day quests (no tilting at windmills here), he provides tips for completing them, and illustrates his points with interesting vignettes from his own travels, and from interviews with other hopeful questers.
I'm in the middle of my quest to visit the highest natural point in each of the 50 states plus DC right now, and this book provided me with some motivation to keep going. (It also gave me plenty of ideas on what to pursue when I'm done!)
Note: I received a copy of this book from Blogging for Books in exchange for a honest review.
