There are no tricks. You likely know the basic rules. Reading a bunch of books won’t help you start.
You need to start writing. Do it lots and do it often. After writing, look at it after a few days or months and figure out ways to improve it and make it better.
Show it to people. Listen to what they think you wrote. Don’t argue. Decide what will make it better.
Enjoy doing it. Otherwise, you are doing it for the wrong reason.
Start young while time is on your side.
Don’t get caught up in your own headgames. They may only lead to not writing.
Not writing is not your goal. Writing is. Don’t forget it. It’s amazing how many people do.
