So a friend of mine recommended Obsidian ages ago and I looked at it but thought I was happy using Joplin (another text-based note tool) which I still think is a great app. Took a brief look at it and thought it was just too complicated...
Then recently, I went down a youtube rabbit hole watching videos of how people use Obsidian... OMG 🤯
Now I have 2x Vaults, one for work and one personal. Dataview, templater, quickadd, periodic notes have just changed everything. Now I have documents for each person at work with their basic info and then when I make a meeting, I can just tag them which then updates a dataview table that shows what meetings I've been in with them.
Tasks allows me to just create a bunch of todos in random notes and then I can create a table to show all my undone tasks.
I mean, why did I wait so long? I've been using it for about 10 days now and it's been such a game changer. Sorry Joplin.
I'd recommend just using whatever cloud backup tool you have access to (Dropbox, google drive, whatever Microsoft's thing is, iCloud) or setup something like Syncthing. I use Syncthing and sync it to my NAS which seems to be working well so far.
