I know this thread seems to be Obsidian specific, but wanted to share: I've been writing down every detail of my day since January 2021 on Diarly. I pay $15 a year to have it sync across iCloud devices. I have two "journals" - one for personal, and one for work. From thoughts, to encounters during the day, to what food I ate, I write everything. It has dramatically improved my day-to-day. I've had trouble remembering my whole life, and now I can just look back and find the exact date where I did something (the search feature is pretty spot on). It's even improved my retention skills - e.g. "i don't remember what day this happened, but I am positive xyz happened because I remember writing about it". Strongly strongly recommend it to all.
