Insecurities

We hold the keys to our own chains,
These tendrils spread from our hands;
Carping words from our own mouths,
But courage, the heart expands!

These little battles we win each day
Coalesce into a war.
Pallid dreams of impervious nights
Evince, ask "what for"?

The preponderance, the impertinence,
The hegemony, hence,
The invectives, for each precious flaw
Are razed in their defense.

-PS: this was a vocabulary activity I had to do last year. Props to you if you knew all of these words in this context.
