In recent months, I have radically cut back, some days I don't have any coffee at all, and other days I have my first cup in mid-afternoon.
Perhaps, my lack of drive is just plain old "Why bother?" syndrome.
In the words of a song I built a wall so high, I can't so over the top. In the beginning it was hard not to write, but as time went on it became harder to write than not to write.
