1. you choose a fixed duration of time within which to journal (i choose 15 minutes even though it is initially tough to spend all of)
2. if you stop typing for more than a few seconds within the duration, you lose your writing
These constraints basically force me to dump anything and everything on my mind for the sake of continuous typing (to not lose what i've written), and I've been successfully doing it at least 1-2 times a week for a few years now. All your entries are also saved locally in-browser only, with the option to export a savefile. Source code: https://github.com/krrishd/write
I've written about this in more detail here: https://jborichevskiy.com/posts/journaling/
When I try to imagine my ideal journaling tool, I think it would be a desktop (and mobile) app with two distinct modes:
1. Distraction-free, focused entry. A blank entry and a blinking cursor. This is great for very open-ended writing where I have no idea where it will go - just stream of consciousness and following it. Usually in this mode I'm in a comfortable, quiet environment (my room at night, coffee shop, hotel).
2. Ideation/connection/writing mode. This is a hypothesis I've been meaning to test in more detail but I'd be curious to have a mode where as soon as I type a word or a phrase, I instantly see previous references to this top float up from below, links and references I've saved to the right, email discussions I've mentioned it in, tweets I've liked about it. Basically, frictionless access to other thoughts and formulations of the idea I'm thinking about to make writing about it easier. I don't know if this would actually help matters, but I am curious to try (or build) something like it.
"Funny, I just ordered a pocket notebook for the first time in years today. I'm curious to see what contingent of people on HN still use a physical notebook. I also use orgmode extensively to keep track of my intentions, media preferences, notes, and stray ideas, but it doesn't really scratch the same itch as a physical notebook.
The reason I had to order a physical notebook online is because I wanted a pocket notebook with no lines, dots, or grids on the pages, which is surprisingly hard to find. I'm attracted to the non-linear approach to notebooking, and plan to fill this one with content in a random page-order as things strike me. Sometimes I just have a cool thought or sentence, or just want to slowly fill a page with something, and it can really help your creativity solidify to have a trailing log of your weird random inspirations. Sometimes I just transcribe lines from a song or book I like, or write down something someone said. Some pages are just geometric shapes. Rarely, I'll make a simple "today this happened and this is how I felt about it" page. By the time you fill it up you have a really organic document that can help you understand what makes you unique and what you like / care about in your daily life, without the stress of writing a cohesive or linear work."
The reason I shared this here is because I'm not entirely sure that software can replicate what I'm looking for from journaling. I'm just not likely to look back through entries in a software format, or treat it as anything other than a log. The most flexible solution I know of is probably TiddlyWiki, although even with TW you can't get that direct-to-brain connection you get from pen and paper. I may be an edge case though, good luck!
