In addition to teaching here,I also teach at a smaller high school 17miles down the freeway from where I live.One day a few weeks ago I was driving to that school when my car broke down just after I exited the freeway.I was only about a quarter of a mile away from the school so I grabbed my books,and started walking.
"As soon as I got there I called a repairman to meet me at my car after class.One of my colleagues asked me what had happened.'This is my lucky day,'I replied,smiling."
"'Your car breaks down and today is your lucky day?'She was puzzled.'What do you mean?'"
"I live 17 miles from here."I replied."My car could have broken down anywhere along the freeway.It didn't.Instead,it broke down in the perfect place:off the freeway,within walking distance of here.I'm still able to teach my class,and I've been able to arrange for the repairman to meet me after class.If my car was meant to break down today,it couldn't have been arranged in a more convenient fashion."
I once read somewhere before that every morningwhen you get up,you have a choice about how you want to approach life that day.And this is what I choose——to be careful.
