My Friend, the Duck

My friend, the duck, does not know why 
We curse and quiver as we do: 
He asks me, if we'll, by-and-by 
Learn how to calmly think things through 

And glide the way we're meant to glide. 
With answers, though, I've had no luck:  
For we, the people, try to cover 
When we've never learned
