For me, happiness is a transitory, intense positive feeling. Most of what i call happiness in everyday conversation is really "contentment". I have what I need. My lot is what I can deal with and grief or anger are not regularly occuring features just now. I have a good home, loving family, satisfying job, and yeah, there are small things I would change, but they dont' eat at me.
"Happiness" is nice, but I don't think that I can build a life looking for it anymore than I can build a life hunting "adrenaline rushes" Yet i feel that in general, I am what most people would call "happy" (if not coherent). Do I make sense? Huggs!
