Better Something Than Nothing

It is late in the night, and I feel I should write something for the sake of practicing my writing skill. I started to write journals last year, hoping it could, to some extent, help improve my writing skill. The good news was that I was able to develop the habit and keep writing some random and simple things every day. However my writing skill didn't benefit from it that much, because I didn't get any constructive feedback about my writings (it is understood that your writing is the subject of the sentence; writing is always singular, never writings).
Feedback is critical to me, since I am not able to assess myself properly when I write in English. I only know what I write is not good, but I don't know what kind of things I can do to make it better. I didn't (did not/didn't = at one time, have not/haven't = as a habit or at more than one time) read enough English books, and it was also something limiting my writing skill.
I really should spend more time on organizing the contents (I think you mean the content [of my writing]) so that they (refers to the contents, but if you mean the content [of my writing], then use it) can be delivered in a more cohesive way, easy for people to read and follow. However since it is late and I am sleepy, I will just write whatever comes to my mind.
It is better to write something than to write nothing. I will try to write something here every day.

Your writing is excellent, I'd say at the University level. You use advanced vocabulary and sentence structure in a very natural way. So these are not corrections as much as style suggestions.

It is late in the night and I feel I should write something for the sake of practicing my writing skill. I started to write journals last year, hoping it could to some extent, help improve my writing skill.

The good news was that I was able to develop a habit of writing journals and I keep writing some random and simple things every day. However, my writing skill didn't benefit from it that much because I didn't get any constructive feedback about my writings.

In speech with friends: The good news was that I was able to develop a habit and keep writing some random and simple things every day.

Explanaton: It's okay because they you and your friend are on the same topic, but in writing it's different. Because you have to repeat. 

Feedback is critical to me since I am not able to assess myself properly when I write in English. I only know what I write is not clear and I don't know how I can improve my writing skills. I can do to make it better. I didn't read enough English books and it limits my ability to improve my English.
