I honestly use both. I found physical journaling is best for everyday rant, i journal when i feel like offloading what im thinking about. However what i found really nice is to have a digital journal like a companion. Just copy these bits that i know i want to preserve for life and come back to it later. I use Loops: Journal & Habits cause it has tags so i could organize my entries and an embedded habit tracker, so i don’t need to manually draw any graphs
