Writer's block is just a problem that you need to overcome.
It may not be obvious, it may be the resistance you have over writing because of one thing or another.
You need to find what's in the root of the problem and solve it.
Sometimes it can be as easy as challenging it and prove it wrong.
In my experience, writing has a lot to do with expectations.
I don't have article writing block for a long time, but when I am to write a long sales copy, I still find it very hard to get moving because I expect the perfect copy even on the first draft.
Sometimes it took days or weeks before I found a hook that I really liked.
I have learned a few things since then.
If I keep writing ideas and research information down on paper, it may help me generate more ideas for the hook and content later.
I can start anywhere and do other things as well to keep the momentum going and make the flow smoother.
The same thing applies to article writing as well.
If you think you must have a perfect opening paragraph before going to the content, if you think you must have a perfect idea before writing the first article, it may take months before you write your first article.
To have a great idea, you need to have a lot of ideas.
Every idea may be good enough for article content, because you never know which idea is going to work for your audience.
Just by writing and keeping at it will you find out later and get all the readers you don't have if you don't start writing.
The point I'm trying to get across it simple.
If you feel you have a kind of block, face the reality.
Use article templates or skeletons to help your in writing in an organized way.
Research to find more information.
Often just one single story or research data can be turned into a few articles, if you keep the flow going.
