One thing that is missing in your life that's keeping you from complete happiness or satisfaction. For me, it would have to be a loving family or love in general. I've always had a relatively small family and it's just been getting gradually smaller as years go by. I lost my dad in 2009 to cancer and my mom doesn't really do much these days in her 70s. My grandparents have all passed away and my only sibling is going through a divorce. I live alone with no family or kids of my own. Even though I'm fortunate in many ways, I sometimes wish I had a bigger family that I could bond and do things with (I'm very selectively social). I just think I would be in a better place mentally.
