I started writing at ten-years-old with the sole intent of mimicking my older sister. She found FanFiction.net and started writing fan fiction on there. So, I started writing Teenage Mutant Ninja Turtle fan fiction, and she was kind enough to let me post my story on her profile - despite how horrible it was! Somehow, somewhere, writing stuck with me all those years.
It's changed drastically and yet, not at all. The main difference is that my craft has improved naturally simply because I'm much older than my 10-year-old self when I first began writing. I always wrote dialogue-heavy and tried to change that about myself because most readers love description and pretty scenes. However, I finally embraced my writing voice and style that's unique to me and my writing is about 75% dialogue and 25% description. Description occurs through the dialogue, which is easier for me as a writer (and reader) because I don't picture things in my mind. I still practice description writing, of course, but I think I've found a decent balance over the years between dialogue and description.
Of course. Writer's block happens to every writer. My best advice to overcome it is to let it happen. The way I see it, writer's block is your friend; not foe. There are two types of writer's block: the one where your brain is telling you to take a creative break. So, step back from the computer and stop working for a bit, even if it's just an hour. The second is where your brain tells you to take a break from your current project. Maybe you've been starting at it too long, spending too much time figuring out that plot hole or timeline, whatever it is. Give it some space. But, if you're in the mood to keep working on something, you can write those characters in a short story or flash fiction, or you can work on a different writing project.
