Words are created for understanding 
They birth your knowlegde 
But some they create your mood. 
 
They challenge your wisdom 
They mold your lives 
And often your're effected by criticism. 
 
Some words they give life 
And encourage your heart 
To do the best you can. 
 
Yet some are said 
They put you down 
To make you sit up and stand. 
 
Some words depend  
On who says them 
This can develope a mental film. 
 
That plays over and over 
In the back roads of your mind 
Dispite the time they were in. 
 
They are said to change you 
To strenthen your backbone 
But instead it weakens the flesh. 
 
So what do you do 
To honor contructive critism 
When actually it hurts the heart. 
 
You tell the world to take cover now 
Because you're in charge 
Of making a new start.
