Absolutely true @jaynie; I believe we are all about as happy as we decide to be... as the years wear on, happiness is more a choice/action we embrace than a "thing" that happens to us.
Most often, happiness is a consequence of gratitude... which is also a practice; a form of mindfulness of when good things happen, rather than allowing ourselves to become absorbed by negatives.
Ack! No, I really wasn't trying to come off sounding all "guru-ish;" I'm so FAR from that... but I think you know what I mean.
