You're so afraid you're somehow doing it wrong—when you first set out to write.
You make sure you read all the books on writing you can possibly read.
You make sure you emulate as many of your favorite writers as possible.
You make sure you talk to all the people who have writing experience.
You make sure to prepare before you start writing anything.
You make sure you make sure you make sure...
You want to make sure you follow the right path.
But you don't need a path to follow your path. You simply need to write. And write. And write.
And slowly, day by day, word by word, you will make your own path. One day you'll stop, look back, and see how far you've come. How long your path is. And how you were the one who has created it.
