What is Happiness - Unrelenting Question?

Yesterday, I was with my good old friends Kat and James, whom I've known as two single people to their current state of parents of beautiful blue eyed Jack. Spent a lovely sunny afternoon with the trio, and it got me thinking, are they experiencing true happiness? I think they are. One look at Jack was enough to flush away all your troubles and provide the happiness that no riches can acquire. I think their own not so happy family situations as children caused them to pursue this life at an early age and my childhood complete with beautiful memories with my parents and sisters causes me to chase another kind of happiness. I am very aware of the fact that this path will bring loneliness to my life, but I want to take this road less travelled, the road without the proven success record.
