You Are Not The Code You Write
This is important wisdom to remember. As a new developer (and as a blogger for that matter), it's good to write bad code (or posts). Even if only to get it out of your system so that you can get on to the good stuff, you must focus on execution.
Grappling with code in your mind, or being afraid of writing inelegant code/prose/posts hampers you from learning from your mistakes (or first takes). Anne Lamott, in her amazing book on writing, Bird by Bird, emphasizes writing no matter how bad it may seem at first. It's like the first squirt of a toothpaste tube - messy at first, till you get to the smooth bits. As long as you show up, you're doing your part.
Take the criticism as a challenge to do better. Then do better. You can be wrong: as long as you then do the work to fix it.
Things to think about.
