With no argument I think most people agree
With the adage stating that, "you are what you eat"
But it's possible there's information not known
Having equal importance or maybe more so

All the nutrients eaten; We intake our food
It will travel through digestive tract once consumed
Same can also be said of our actions and thoughts
They're the building blocks making up all that we are

Brains are not like a rigid or fixed type machine
An old dog and new tricks go together it seems
Our plasticity will let us both change and shift
It makes pathways; New neural links over the rifts

These connections might possibly benefit us
But this same mechanism can also do stuff
With a negative scope, the outlook and belief
We might think we're no good; Our lives filled with much grief

If we're constantly saying things inside our heads
Like self-doubting, self-loathing and feelings of dread
Then our brain will re-wire to fit this outlook
Once ensconced in this spectrum; Not easily shook

The same way that a person engages with time
Like activity, also is true with the mind
A small change in the way that we look at ourselves
The new thoughts and beliefs in our mind start to meld

With the make-up within that each one of us holds
Self-beliefs and self-doubts from our birth till we're old
Like a painter with ink; Our brush never is dry
We are always creating what's in our mind's eye

So don't hinder yourself with a picture that's bleak
Just believe in yourself and go get what you seek
You are capable of so much more than you know
All it takes is belief and in time it will show
