Whats a pessimist?

My mom calls me a pest in this,
and others call me a pessimist...
maaan these complicated words put me to sleep like a seditive,
no time to learn whats a pessimist,im juss one in a million specimen.
Im either lost in the patterns which fate repeptitive uses to kick my ass...
or im getting my ettiquette out in the subject and the predicate,then these rhymes amass.
But they call me a pessimist and oh alas,
i dont know what it means,though ive been through english class.
Dont know bout bein a pessimist,im juss another loser thats lost,
and so im a saviour to the winners,coz they win their wins at my cost.
Man i aint a pessimist,i dont even know what it means,
im juss another one of those dudes whose lost so much,hese afraid to dream.
Im just that dude who ever ever tries to smile,
but i tell it like i experience it,every gotten while.
Im a guy who laughs and plays,
in if a jokes on my mind i cant stop from sayin...
im just that dude who cant be too depressed to let the sadness prolong,
though sometimes when it gets hard,i feel lifes too long.
and they say and say that im a pessimist,
but i call a snake a snake and recognize the venom for what the venom is.
The whisperer whispers and we find our selves clinging to this life,
but this world cant never be perfect,even if your a winner with kids and a wife.
Im juss a dude seeking reality,but whats a pessimist,
when i seek realities i see,if theres a reality then death is it.
But that dont mean im goin out with a cut wrist,
naa im just dealt my cards,just sometimes its hard to adjust with.
Sometimes the game can get rough from time to time,
so to stay sane i get it all off,and out in my rhymes.
The word pessimist seems only a dictionary away,
but im guessin i aint a pessimist,im just a visionary that prays.
I pray as much as i can,5 times a day,
so the devils attack,from more than 5 types of ways.
But maybe the brothers are right,maybe pessimism i dont lack,
but i say like muhammad ali said "if thats somethin good,then im that"
