Complacency, zen and nonsensical rambling on the same chord

I am wondering about my mellowness these days. Perhaps it is getting slightly older, maybe it is my children, I don't know, but I have become more and more laid back, kind of go with the flow. I can't put my finger on it, but so many things that would bother me before just don't even cross my mind now, its wierd. I think what got me even thinking about it was running into someone whom I knew and they mentioned chronically returning stuff, and I thought "yah, me too", but really I don't do that anymore. I used to, never quite satisfied with this or that, obsessing about things, as an outlet for work stress, just enjoying having money to spend. I think so hard about my purchases, finding the perfect item, that I am satisfied when I get it, like reaching a goal, and then I think about it no more. I used to get so irritated when things I bought weren't perfect or things in the house weren't perfect-now it just doesn't matter. Then somewhere in around Dad's illness,I have learned I guess to accept and yes, enjoy imperfections for what they are-part of life, and to really fully enjoy all else around me. My home has been my sanctuary for a long time mind you, getting home on a stressful day was like a big exhale. I could completely forget all other stresses just playing with the kids, and mellowing out with Dave and our nightly rituals. I think also that having children and enjoying their numerous perfections and imperfections as part of their personalities has maybe helped me to realize so much of the materialistic crap I used to focus on is not important. I still enjoy shopping, it is relaxing. I love re-organizing the house-moving around furniture and getting new furniture just freshens things up, change in that sense is enjoyable. But I lost some of my retail zen in favor of a different kind of inner zen, a deeper satisfaction with who I am, and where my life is at. I can be satisfied with where things are at because life is so unpredictable at times. What I mean is, so many external factors in the life and death cycle are beyond my control, what I can control is how I feel about things and how they affect me. My family have brought me to my inner sanctum I guess. The restlessness, perfection-seeking self of my twenties is really gone. I am glad of that, since I am almost mid-way through my thirties!
