Stop editing your work as you write. This is a common cause for writer’s block as you delete everything you write and then find yourself stuck with nothing. Even if what you are writing sounds bad, get it down on paper. The hardest thing is to write with a blank sheet of paper. I have found that forcing myself to get past the part that is causing the issues is the best way to beat the problem. I then get to a part that I love to write and it flows really easily.
Once you have something and have reached the end, that is the time to go back and edit your work. You may find that you have to delete everything you forced out but at least there is something there to rewrite and work on. At least you know what you wanted to get from it and can work on it from there.
There was one part of my non-profit project a few months ago that I just had to force the writing out just to get past it. I sent it to m beta reader, who was surprised that it was forced because it read really well. I’m not completely happy with it but at least it works and I could move onto the next part.
It is possible to get over writer’s block. Eventually, you will find something that works for you. Exercise and taking a break is the most common option but sometimes you find you have to force yourself to write past it. Avoid focusing on the deadline looming and get your mind into the right mood to write. You will soon find that your content flows.
