I love writing and it is what I feel I am the best at. When I finish this life, I want to leave behind a positive legacy through writing Fantasy and Science Fiction. Particularly, I would like to write in a way that will lead to greater depth of thought regarding paradigm shifting philosophical questions. I honestly believe that some of the worlds biggest problems are rooted in the rapidly increasing superficiality of thought among societies.
The problems that I encounter the most when I try to write are self-doubt and depression. I find it difficult to actually sit down and begin writing, as I have a bad habit of immediately beginning to over-analyze and over-criticize every word that ends up on the page. Have you ever dealt with similar issues, and if so, how were you able to overcome them?
I always love to get a writing question mixed into these, so thank you! This is actually an extremely common problem for new writers--perhaps the most common. (Though the second most common is the one I had, which is the reverse--that of never wanting to do revision.)
What's happening here is that your ability to recognize good writing has outstripped your actual skill at making it. This can be super frustrating, because you know stories--and you can physically do the act of writing. You've been learning that since grade school. Yet, the story you write doesn't quite live up to it.
Mixed with that is likely an over-critical eye, treating your work like it is worse than it actually is.
I often use this metaphor: I played trumpet in high school. I'd played since fourth grade. Senior year, I took jazz band, and fount it extremely frustrating. I knew how to play trumpet, and I could hear the improv jazz riffs in my head--so why couldn't I make them come out of the horn? Everything I actually managed to produce felt pedestrian at best.
The answer is both mental and procedural. The mental side this this: Recognize that what you're doing right now (by writing) is NOT producing your grand masterwork. It's the equivalent of sitting down in your garage with the trumpet and stumbling through riffs until you start to get that important connection between brain and instrument that lets the vision in your head actually flow unimpeded.
Don't think of this writing as something you're going to sell, any more than you'd tape and record your practice music sessions. Don't think of what you're writing as "wasting" an idea or "failing" at a story--you can and will re-use these story ideas in the future after you figure out your process. Remove the performance anxiety, the need to be great from the get-go, and the expectation that your first draft needs to look like your favorite authors' final, published draft.
As for procedure, try some strategies that work to limit self-revision while writing. Try writing stories longhand, both to separate yourself form computer distractions and to make it harder to revise. Try going to a specific place to write, like an office or library, and treating your hour or two there like work time--a destination for writing. Make good habits, be consistent, and note the things that work on some days to make you achieve your goals.
