I've been writing in English for some years, and I manage to do it most often.
However I also have noticed, sometimes, when I am tired, my mind is distracted, I cannot focus on the main aim of writing the article.
When I lose my concentration, the post if out of its subject.
I'm Chinese, writing and thinking in English to describe and craft seem to take more concentration.
So, having a rest, and create a blank page to refresh my mind is what I do sometimes to regain consciousness.
This article is written when I am tired at 7:29 this evening. I should write more concise and precise tech articles to illustrate my own crafts, and sharpen my designs or app buildings. This is a bit challenging for me.
