The Sweet Spot

On and on this pattern goes. A curve with a sweet spot in the middle. The optimal amount of calories to consume in a day. The volume at which you will enjoy your music most. The right brightness of light to illuminate a room. The number of friends with whom you can have a meaningful relationship.

Great points in here about finding the right balance in many areas of your life. I particularly found the running curve apt.
