I feel for you man I really do. I was also a single Dad taking care of a girl from about age 5 on.
I think life is kind of a series of photos that we can replay in our mind. I also think the time between the memories are the most important bits of time even though we do not remember them.
I guess what I am saying is even though what you are doing is may not be a photo moment later in life you might stumble across a silly tea cup that brings back feelings and make you wish that you had done more. And knowing that I will hug my kid and tell her no dating till I am dead and that I love her.
Life is good. Not every moment, but if that were the standard none of us could be happy.
I have so much fun with her every day that it's hard to imagine how I got by without her for the first 40.
You are right, it's not just the specific points that are important, every moment is important and should be enjoyed.
To be more specific, the non kodak moments become more important simply because it's the everyday things that really help shape what sort of person our kids become.
If we lie and cheat, they think it's OK.
If we go out of the way to help people, they think that's the norm.
What you do when nothing special is happening is in many ways the most important things that we do for our kids.
My hope is that my daughter loves hotrods, fishing, hunting, shooting and some day, way way down the road, having a high quality beer with the old man.
