Musing about happiness

I do wonder if happiness is overrated.  I wonder that because happiness seems out of reach for me.  At least that is what it seems.  I am just wondering about that as I was watching a performance of "Happy" by Pharrell Williams.  He is a talented singer and producer who sang a great song.  The problem is, with all popular songs, they tend to run their course.  Over time, people in general get sick and tired of the same old songs.  Interestingly enough, that is how I have felt about my life.  Maybe I am depressed about something I have no idea about.
