Today's troubles

There's this scene in the movie, Zorro, where Antonio Banderas is being taught to sword fight. He is told to keep his focus within a small circle drawn on the floor. As his skill improves, the master says, his range will broaden.
It seems to me that the opposite is true in life. The more I learn, the smaller my circle gets. What I mean, is that I actually have to force my scope of reality to be much smaller than it could be. Otherwise I freak out. If I concentrate on what is right in front of me, I panic less.
My worries could include:
Where am I going to live?
What am I going to drive?
How am I going to pay my bills?
What am I to do with the men in my life? Or lack thereof.
How am I going to parent through the teen years?
Or,
I could shrink my circle to include those issues right in front of me.
We need to eat breakfast, and start school. Then, when that's done, we'll do the next thing. Like lunch. Blogging obviously fits in there, as well.
You see, purchasing a retirement account is not an option today. Educating the children is.
I think that is what Jesus meant with the whole "be anxious for nothing" thing. It's counter intuitive, and countercultural. But it seems to work pretty well, when I do it.
Perhaps it's also what is meant by the Psalmist who wrote that God's Word is a "lamp unto my feet and a light unto my path." It's like having a flashlight on a late night trail. I can only see one or two steps ahead with any clarity, so that's where I put my attention, and my feet.
Step by step, little by little.
Keep it simple, stupid.
