(This was an exercise I did for my creative writing class.)
I write as a content creator. Compared to what I felt about writing in the past, it is now the polar opposite. I used to hate it and felt like it was a waste of time. However, I now feel that it is one of the healthiest ways to express yourself. I write fantasy stories and publish them for people to read. I really enjoy creating the worlds in my stories and interacting with my readers. It motivates me to keep improving my skills.
I love writing in the fantasy genre as it is something that truly enthralls me. I get absolutely absorbed in the idea of magic and inhuman abilities and I can't stop reading or writing about them.
World building is also a really cool aspect of writing fiction. Rather than writing in our world that already exists, I enjoy launching myself into an alien world with unfathomable physical laws that don't fit in reality.
One last thing that really keeps me sucked into my writing is that there is so much freedom in creating your own world. You can do so many things, create countless people, set your own rules, create your own places, and explore the dynamics between different characters and places.
