why are we nosey?

I don't even know that nosey is the right word for what I am feeling or what I have been thinking about...I find or I personally feel that if we worried about ourselves and how we are treating our VERY OWN family members then we wouldn';t have time to worry about what our neighbors are doing or saying and who they are with.
I hae been reading alot of things about marriages and I am certain that all of us at some point think we are out of love or have ran out of interest together but we need to take time to refresh things and that takes work and most of us don't want to give "OUR" or "ME" time to work on such things. It has been so long since many of us have taken time to sit down and rethink what our goals as a spouse, father or mother or sister or brother or friend are that we just stay in that comfort zone. I know that when Maggie is gone it is going to be a sad day because Danny and I have not worked on many things that we should have and now it takes even more effort and countless times of not opening our mouths and saying the wrongs to try and make things good. Life is work, marriage is work, friendships and work, children are work and being a neighbor is work...so if you are lazy then life is going to pass you by and you are going to be very lonely and bored most of your adult life. If we are lucky we have an education, family and work all figured out before we turn 55 and then the rest of our life if you are not careful we are going to try and figure out what to do with the REAL EMPTY NEST SYNDROME. I not one that believes in a lot of medicine things I think that our forefathers lived and seemed like they made it through a lot and succeeded so what is our problem...don't blame it on society because we are the only ones that can do anything about our situations. I have a feww good and ture friends that I share a lot with but for the most part my life is my family and hoping that I can get my daughter or I should say OUR daughter raised with good standards and morals. I kow that God has only blessed me with that one because of Danny coming into my life when I was in a dark valley but I haven't lived up to the things I thought God was giving me back and that is why I am feeling all of this. I have a step-daughter that doesn't know which end is up and is having children like she knows what to do with them and the raising part if definitely interesting. Then I have a daughter that probably doesn't know what her life should be full of because I have not always done everything I should have been doing to make her worthy of so much...but I am trying to set my record straight it just isn't going to happen in an evening. Then I worry about my family and their families and I wander where we are all going to be in the next life and it scares the hell out of me.
Why can't people learn by mistakes their ancestors have made or why can't we truly want better for our children...and grandchildren and future generations. When they say the flesh is weak so is the mind and heart we are not the strong people we always portray.
It is scary that many of us don't know what to do with our life and or we take so little time when each new truimph or tragedy happens to re-evaluate and start over with what we have gained or learned. I was sitting in church today and looked around to find I don't have it has bad as I think I do sometimes and that I am luckier than most. What we take for granted is sickening in this country and in our own lives and in the lives we have with our Father in Heaven. We don't even take time to usually give back to anyone I don't know that we are truly good about thanking others when we should.
