To what or to whom do I owe a thank you?

I got a call today from a woman searching on behalf of a hospital looking for a photographer to create headshots of at least 26 physicians.

I want this job.

I asked her "How did you find me?"
She said "In the phone book."
"Oh boy, am I glad that works!" I said, insinuating that the cost of advertising is high.
"Oh yeah, I'm old school, I use the book." she replied.

I gave her a quote that should get me the job, and I hung up and thought about how this year I don't have an ad in there.
No one in my industry does. Times are changing. The internet is here.
Almost everyone who calls says they found me on the web.
I think about how next year, when someone like her is using the 'old book', I won't be in there.
I lay down, put my hands over my forehead and accept the future as it waves over me.
