Being a writer means one, and only one action - writing. Everything else is things in themselves irrelevant to the writing process itself, or inseparable from it. There are several terms that are often mentioned in connection with writing - primarily inspiration, and then technique, originality, or even genius.
Inspiration is the first term to be uncovered. Every time you think you can't write due to lack of inspiration, remember all those moments when inspiration came, was there, and left, without clinging to the whiteness of the paper.
Inspiration often occurs during the writing process.
Write about what you know. It involves feelings and inner experiences. Write about anger, sadness, hurt, relief, lust, bliss. Write about everything you have ever experienced and felt deeply.
Originality will come by itself when all obstacles are removed from the road, when an independent voice breaks out. Everyone is created for something that is unique; it is only necessary to remove all the excess in order to get the most beautiful (and most permanent) ornament from the rough diamond.
You are right that you should write about anger, sadness, injury, relief, lust, ecstasy. About everything you have deeply felt and felt. I have discussed very important issues.
