So...thoughts on being a writer...
-I wish someone had told me how many drafts go into writing a story. There's the first draft and you rejoice that it's done! And then you read it and wish someone had told you what a terrible writer you are. A friend talks you off the ledge and then you revise and rework the story. You re-read this second draft. It's not so awful. Maybe you can still save it. Seven drafts later, you're pretty happy with the story you've written. Writing is an act of passion. Editing is an act of patience.
-Not everything you write will be published. And that's okay. I've heard of people who have never shown anyone their first attempts at novel writing.
-Make sure to have a support group of readers/editors that will tell you the truth. It's a great thing to have friends to encourage you and listen to your plot twists and character shenanigans.
-Write a story that you want to read. If you don't, you'll hate it each time you read through it. But don't write something so precious that any attempts to change it / edit it will lead to you self-combusting.
-Write what you know. This is a tried and true fact. If you don't know about xyz, it will show on the page and the reader will know that you don't know what you're talking about. Pause the writing, research the time period / clothing / weapons / readings of mass spectrometers, and then continue writing with confidence.
