I'm proud that I can write pretty much any poetic form I've tried. Some better than others, but I can manage something at least.
I'm proud that I can use other languages in poetry, sometimes snippets but other times the whole thing. I once won an award writing poetry in a language I'm not even fluent with.
I'm proud that my characters can make readers cry. I hear that fairly often in comments. Readers really care about my characters. Okay, so do I. I'm proud of that too.
I'm proud of using writing as a learning tool, like the shared-world Torn World where I practice teamwork through collaboration. Fiction, poetry, nonfiction, it's all good there. And that's different than writing alone, and I enjoy it when it goes well. It doesn't always. I haven't quit yet though. For me that's an accomplishment; I'm not a joiner.
I'm proud of writing things that people love enough to share with each other. Sometimes it's posting links, or giving my books as gifts, or sponsoring poems so others can see them, or copying things for a friend to read. All kinds of ways. They care enough to spread it. That's how cultural transmission works, so it makes me feel good.
I'm proud of being unstoppable. Sometimes the world is crap, but that doesn't stop me from trying to make my corner of it brighter, fiercer, better. I will always have something to say about it, and I will always say it.
I'm proud of doing the impossible. People say there's no money in poetry. I made there be. If this were pocket money, it'd be a success beyond my wildest dreams. As household support, it's a drop in the bucket. But it's still impossible, and I'm still doing it, and I'm still proud of it.
