Doubt (a poem)

I cause the hand to falter
I dissolve deep-set resolve.
I am the halter that restricts 
The gallop of your hooves.
I declare my opposition
To each heartfelt proposition;
I undermine all innovation
With consequential whispers
And smirk at hesitation.
I rot the roots of confidence;
My sneer is the frost 
That withers new shoots.
I thrive on fear, 
the trembling hand, 
The quivering voice
The nervous tic,
The shiver.
I oppose each fresh  decision
Regardless of conviction
With derision
And you will find
That I will win.
No doubt.
