I am the underdog

Inspiration: Someone asked me for a college textbook for free...?
Word: Poor

I
am a poor man
in a rich man's world

I
am a quiet man
in a loud man's land

I
am a still man
in a quick man's field

I
am an unlearned man
in a lettered man's universe

I
am an unfit man
in a fit man's arena

I
am an ugly man
in a good looking man's society

I
am an imperfect man
in a perfect man's realm

I
am a content man
in an unhappy man's world
