You are a writer, just lazy.
I enjoyed "Conversations with my Therapist."
You have the most important thing, you pick good topics.
Now the grunt work, write it, re-write it, wait a month and go back, re-write again.
The art of writing is first take out the garbage. It is not hard, humans have small storage, and when that is gone, a large flow.
I know the page and a half writer, recycled garbage. Try thirty pages, flush out your head.
It takes mental exercise to think in chapters, book length. The first one is horrible.
Not to worry, it can be hidden. The next one starts with the larger format, and things fit better.
Mark Twain spent thirteen years on Huckelberry Finn, or Tom Sawyer. I know the feeling, I started my book when about your age, and am getting it right fifteen years later.
I have enjoyed it all, and kept growing. All of those hours of me overcoming being me.
Write about anything, the dust on the window sill, for an hour a day, and you will get the bad out, and learn what you do well. Others go to the health club, work their body, writers go to the keyboard, and work their mind.
It is an unlimited mental outlet. Nothing is more personal, something like turning yourself inside out.
Months later, when I read my stuff, I find it hard to believe I wrote it. Some of it is good.
When I write of other times, I go look them up, expression plus education. Your love of travel, knowing of other places, can fit in a story, where it becomes the site of the story, a background that also tells a story. Writing comes from within, and the more you write, the larger the inside space, and the more orderly.
It is like anything, we learn one step at a time, then use the same bow that ties our shoes in gift wrap.
A writer's tool kit is within, and in seeing what is without. The observer/reporter, who takes in the facts, then gives them form and meaning.
Write a story about three people, from the outside observer point of view, then write it over, from each characters point of view.
Writing is only a tool, Story Telling is an Art.
It does get to the point where I want to go to work to get away from my writing. It started the other way, but it grew. Now I rest, eat, exercise, for weeks, before a rewrite, for I know it is going to get intense. I will put out everything to total exhaustion, day after day, through hundreds of pages, impossible to map, but it can be done.
Then I will print it out, and leave it on the shelf for six months. Then I read it as a story. I let that sink in for a while, read it again, ponder, and in the next rewrite, my mind has a thousand small changes to make, and did not bother to inform me. Sometimes, I am just the ape with the fingers.
Writing brings out things we cannot even express to ourselves in words. I think the word part of the brain is very small. The slight changes in word usage bring big changes in the feelings evoked. I do not know how to be a non-verbal writer, I have no words for it, but I see it in action.
Writers explore the known, and behind everything known is something else. When we start working that border, it gets interesting.
