Does Writers' Block Exist?

     Yes, it's a question. I keep hearing this term: writers' block. But it's like so many things that have no form or substance, things that are only ideas, concepts ... sometimes euphemisms for something else.
     But here's what I've concluded about writers' block. It's just the term given to one side of the writing cycle (I'll call it the ebb and flow) ... the ebb side, when time seems to go in reverse and thoughts that were previously flowing smoothly from the writer's mind to his fingertips and onto the paper (or the computer screen) suddenly stop.
     I often get a visualization of an experience. Meaning, I attach a picture to a set of words that my mind formulates when I experience something, be it physical, emotional, psychological. So, when I experience the stoppage of words onto the page in whatever project I'm working on, I think of the first time I visited San Felipe in Baja California.
     I'd never seen the Sea of Cortes before; nor had anyone ever described it to me. Therefore, I found it quite remarkable to arrive when the tide was in and blue-green water filled the gulf to almost overflowing. It was a panorama of brilliant color as far as the eye could see, and I felt as though I were looking at a massive ocean sans waves at the shoreline. But what was more remarkable was seeing the same shoreline hours later after the tide had gone out, and now all I could see was sand dotted here and there with small pools of water. I estimated that if I began walking out toward the sea, I would walk a mile or more before reaching the water.
     That picture is what I see inside of myself as I live my personal writing experience. One day the tide is in and my fingers fly over the keyboard as the words that fill me to overflowing rush to get on the page. And for a while, it seems as though time stops while I write and write and write, thinking of nothing else. Then, without warning, the tide turns. Soon nothing comes from my mind. Nothing flows onto the page. And when I look, there's nothing but sand as far as the eye can see, nothing but a blank page with no words upon it, nothing but a blank mind with no words in it. 
     Using the Sea of Cortes metaphor, the tide always turns. I just wait for the next inward flow that comes as surely as the sun comes up each morning. Then, once again, it's blue-green water from shore to horizon, and the words again begin to flow onto the page.
     So, I ask my question again: Does writers' block exist?
     I say no. A writers' life consists of ebbs and flows, slow times, fast times, words coming easily, words seeming to stop. But nothing ever stays the same. Everything is temporary. Change always happens. A writer can only learn to see the trends in his own writing experience. Go with the flow; go with the ebb. Wait for the tide to turn.
