I'm one person, not a company. If you've read the book, found something useful on the site, or have a question you didn't find an answer to — I'd genuinely like to hear from you.
This is a private subject and I treat it that way. I read every message and I'll reply when I can, though it may not always be quickly.
If you're writing because you're going through this right now and you just needed somewhere to send a message — that's a completely valid reason to get in touch too.
