Field full of shamrocks

I was wrong.

I used to see a field full of clover
I’d sit, searching, searching for four leaves
Four leaves stood for luck
All I ever found was three

I never knew what three meant
Three stood for happiness
I hadn't known I was passing right by happiness
I thought I wanted four

We can spend our whole lives in a field full of clover
Sitting for hours searching, searching for four leaves
Stomping on happiness searching for luck

Now, I search for three and I'm never disappointed
