I made myself a rule: write out of love. And when you love somebody, you have to tell the truth about who they are - not the cute "truth" in your head of who they are, the one where you did everything right and they did everything wrong.
I didn't write the memoir with any sort of intention of feeling better. I wrote the memoir because I had a weird need to write a good story. But once I was done, I did feel better about myself. Not better, just calmer. Because a tremendous onus had been lifted off my day-to-day.
The minute I landed back in Alaska, it was back to hip boots and fish guts. This cultural flipping wasn't easy - especially on top of the post-divorce fighting that was still going on between my parents. But this is why you don't write a memoir at age fourteen.
It's much harder when you're writing about your life, than when you're writing fiction.
My natural inclination is to think in scenes. So that's how I write, and the issue for me is usually: what to compress for speed.
If you want to write in a mature and interesting way, you have to have sympathy for everyone that's involved.
