If you don't then you'll never know how many you have.
Lest you think I'm clueless, I understand the old saying.
It means that it doesn't make any sense to try to figure out how many chicks you're going to have, because all the eggs rarely hatch.
It also means, "don't plan on something happening, cuz it might not". That doesn't sound so lyrical and folksy as the chicken one.
What does all this mean? Is something big happening in my life that is causing me to wax poetic?
In fact, it's just about trying to count chicks.
I have four. Luckily four are easy to count and keep track of.
What isn't easy is getting a picture of them.
They never, ever sit still.
I took over 40 pictures of the little fuzz monkeys. How many pictures were keepers?
And they aren't that good.
Thank heavens for digital photography.
So, in my case I would say,
"Do count your chickens before they hatch or at least get a couple good pictures of them. After they're up and running, you'll never get a good picture of them again."
