Inhale, don't force it, and write down all the thoughts that come into your head.
In this way, "writing" is regarded as a kind of practice, and you will feel it when you write.
When you're just starting to write, you don't have to set yourself too high goals. Completing the amount of writing is the first priority.
When is it better to write?
I have a habit of writing whenever I feel relaxed and comfortable, bringing this ease to the reader, believing that words have their own power. Happiness should be connected, and so should beauty.
Please believe in yourself and in the readers, there will always be someone who will be on the same frequency as you, there will always be someone at the same cognitive level as you, and there will always be someone who will be touched by a sentence in your article.
We keep writing, and we keep moving ourselves forward on the road of writing. Slowly, we will have more and more energy, our spectrum will become wider and wider, and we will connect more people.
Go for it! 
Believe in yourself and go for it! It's not a big deal, as long as you write, you will always improve, and your ability will always improve little by little.
At the beginning, the writing may not have a structure, the subject is not clear, but it doesn't matter, slowly you will perceive the whole picture of your writing structure, even if the structure of the article is not so satisfactory to you, you will find out what shape the structure you write belongs to, whether it is not at all, or it is not at a passing level.
When you know your shortcomings, you can correct them.
You can write about the beauty you feel;
You can also share what you think is right.
Some people are good at writing stories, writing small stories that happen around them.
Write for yourself, write for pleasure, write for want to write.
No matter what others say, we must always learn to walk first, as for how to run in the future, what means of transportation we will do, that is the future, grasp the present, and we must not fail to write because we are not good at writing.
