What is important?

I just finished watching the movie "Crash" and feel very overwhelmed and emotional. All I could think about while watching it was how much I worry about things that just do not matter and I need to enjoy life in the moment, every moment. I could not get my son out of my head and the time I have enjoyed watching him grow up and the pleasure it is to see him learn, laugh and love. I could not stop thinking about my wife and the pleasure it is to be loved, love passionately and have a best friend.
I worry about so much else that just does not matter: work, paying bills, making sure the business is growing; and so much of it I have absolutely no control over. All I can do is to enjoy the moments I have with the people I love so much. Like yesterday, holding my son in my arms while he slept so soundly. This moment will be that, only a moment and I may never get to hold him that way much longer. Sitting with my wife this evening and holding her and watching a movie is an experience that I treasure and should more often.
Do we really appreciate each other like we should? God is no respecter of persons, so why are we? What makes it so hard to see people as just that, people? We are all on the same road of life traveling and trying to enjoy and treasure what we can. I know that there are those who just do not care about others and never will. However, most of us are just trying to do our best and have our own perceptions of how the world works, why others act like they do and how we react to those things. Wouldn't it be nice if grace could change us all to love each other as we love ourselves!
