If you want to get into doing it, I found searching through a lot of note taking applications until I found something I really liked helped me remember to go do it regularly.
For FOSS stuff a lot of people like Joplin, and I could certainly recommend it. Personally though, I really like Obsidian for its backlinking and graph view features, but it’s not open source.
Furthermore, just carrying around a notebook and a pen everywhere you go as a habit helps a lot. I got into the habit of doing this by maintaining a personal journal for some time. For writing effective notation on paper which can easily be digitized, I would recommend looking into “bullet journaling” methods, and again, finding a notebook and pen that you really quite like, helps a lot to make the experience enjoyable and develop it as a skill.
Do you have any recommendations for anyone looking to switch from windows DAW to a Linux DAW? Are there any tips regarding getting the plugins to play nicely?
I would love to switch to Linux on my desktop, but the only thing holding me back is that I use FL Studio with the Arturia V collection and I feel as though it would be nightmarish to try to get such a thing working in Linux.
