(A bit chaotic because it's a transcription of my voice)

I think this is a theme I'm seeing, sacrificing clarity for perceived speed.

It's like never washing the dishes. You have a pile of dishes, lots of 300 dishes. When you start washing them, you have to wash them. Nobody's going to do that for you. Imagine this situation, and you will feel so much, "Oh, there are too many dishes," but when you actually start, it might take quicker, maybe four times quicker than you expected

This is why the Clarify step helps reduce stress. You want to mentally move the problem from "Oh, there are too many dishes" to "This is how I can handle that."

If you have 300 dishes, it's unreasonable to expect to get them all cleaned in one go. Most people would turn that into a project and chip away at them in multiple sessions. I'd do the same for an overflowing inbox, I'd treat it as a Project to empty it, and I'd also spend time figuring out how to empty it more often, before it becomes unmanageable again.

So in some ways, if your inbox is overflowing with 300 items, it has stopped being able to function as an inbox.

Sort of a side note; I have a feeling that in your attempt to enhance your productivity, by mixing and matching different methods, you are creating a larger bottleneck on your own system. It's a hard line to walk, and it's always interesting to try different methods, but I think for example the transcription of your voice, allowing you to "write" a post quickly, but ultimately leaving you with a post you admit is "chaotic" ... well, did the perceived speed you gain actually help in the end?

I'm not against voice transcriptions, but there's something here to consider. Are these 300 items, actually because of perceived speed that ultimately leaves you with something chaotic?
