Book worthy?

I struggle to find the time to write—the one hour of no calls, no interruptions.  Earlier and earlier I rise, and still all I manage is to toss more of my own work out.  The book shrinks.  Again, and again, my books shrink.  So many readers have asked why my books aren't longer.

It's because I whittle and winnow until what is left is book worthy. 

I wish I wrote more that I could consider book worthy.
