Very well written.
I have a similar feeling. We strive for happiness in future but sometimes tend to overlook our current life and how happy things are.It just depends on how you look at it. Lately, I have been wondering what is missing in my life even though I have a great wife, great family, great friends, healthy life (so far:)). I guess it is just a startup itch that I am looking to scratch. Other than that, I feel pretty good.
