From the back end of the book

This is what I wrote at the back end.

The back-end of the book is where I start from
That is because I am too shy, too embarrassed
To say, to show that this is me.
The words I wrote lie in the bin
The songs I write don't see day-light
Goals and expectations were never met
Till today, this soul remains mediocre.
Is it not too late? Or is it worth a try?
Why at all, if everything so far is a failure?
No progress, no sign, no silver lining;
Tunnels, long dark tunnels, as long as what seems eternity.
Here I sing, true to my grey feelings
The ones that always remained in the
shadows. Or is it?
