How can I do it?
Because I know that I can!
I wasn't the one to say I could...
If I wasn't willing to understand.

Embarrassments I withstood.
That did not keep me,
From the challenge at hand.
I wanted this task,
To challenge myself.
I am not one,
To say I will do something.
And then sit and wait...
For an earthquake to shake,
The land before I make a stand!

How can I do it?
Because I know that I can!
I am not the one to say I could...
If I am not willing to be that man,
To do a task I did not understand.
