This is excellent. You make some great points. The habits you developed or refined as a waiter helped you here. This blog itself reinforces your points; the well-developed ideas, writing, editing, formatting, and visuals make it obvious that it was not just thrown together. I found only a few proofreading errors, and I'm an excellent proofreader. "Attention to detail inspires confidence," someone said, and you inspired my confidence to read your blog.
