Verse 1: 
I'm walking down the streets, 
Feeling lonely and incomplete, 
Wondering why the world is so unfair, 
When I'm trying my best to get somewhere. 

Chorus: 
Life can be tough, 
It's hard to keep up, 
But I'll keep moving on, 
Until the darkness is gone. 

Verse 2: 
I had a dream once, 
To travel the world and explore, 
But bills and responsibilities, 
Seem to block the door. 

Chorus: 
Life can be tough, 
It's hard to keep up, 
But I'll keep moving on, 
Until the darkness is gone. 

Bridge: 
Sometimes it's easy to lose faith, 
But I know I have to keep the pace, 
Life is a journey that I will embrace,
And I'll keep striving for my place. 

Chorus: 
Life can be tough, 
It's hard to keep up, 
But I'll keep moving on, 
Until the darkness is gone. 

Outro: 
I'll keep believing in myself, 
And never give up on my dreams, 
For life may be tough, 
But I'll emerge victorious, it seems.
