An ounce of prevention is worth a pound of cure (even in metric).

I experienced over two months of writer’s block many years ago. 

I literally sat at my desk for hours. 

To this day I can  accurately describe that desk. Its vision is before/behind my eyes as I key. It had a red leather top.

I have devised a scheme which I find is 90% successful in combating writer’s block.

Do not complete your thought on page or screen. 

Make sure it is solidly in your mind (make notes if necessary). 

But, do not write it down. 

If it is a description – don’t finish it. 

If it is dialogue – don’t complete it. 

If it is a line of poetry – don’t end it.

The next day, read the preceding page. 

Then slide into the phrase you would have ended with yesterday.  

 Put in those final words. 

The odds are excellent you will continue on your way.
