Such a simply stated question, but such a complex concept to answer! What you said really resonates with me and what I believe, and kind of goes hand in hand with something I was just talking to my youngest about - you can't control other people, you can only control your reactions to them. Might not make much sense out of context, but I do think that we are our own biggest obstacles to our personal happiness.

Great topic and thought-provoking post, @porters!
