An extremely quick read (took me about 2 to 3 hours) and very to the point on clearing a path to finding fulfillment and enjoyment even in things like work, etc. This was part of the Positive Psychology course I took (which became the most popular course at Harvard) and Tal is a great guy with a great grasp on separating what's truly important and how to get there. My understanding is that his next book "Happier" is an expansion on this first one so I'm sure it'll be great also.
