I am tired,

I am really tired,

I am really really tired,

I am really really very tired.

I have done my best,

I have done my very best, 

I have put in my 100% heart and effort.

But what I get back is not appreciation  

but .... .... .... .... 

NOTHING

Nobody see my effort, what can I say? 

NOTHING!

What can I do?

NOTHING!

At the end of the day, what am I?

NOTHING!
