I can’t stop writing

I can’t stop writing
Even if I want to do so;
The posts keep pouring out;
And overflowing the banks;
And why should I hold them back;
Who knows which will hit the sky;
I’ll keep trying and trying;
Pouring and pouring;
And one day, hopefully,
I’ll hit what I want;
Maybe not with a machine gun;
Maybe with a bow and arrow;
Or maybe a catapult;
As David hit Goliath.
