Re long notes/ daily notes. I create several new notes each day (anywhere between 3 and 10 new notes, sometimes more) and I hate cruft. I want each of my vaults to contain useful material, not junk that takes forever to go through.
I still use daily notes, based on a Daily Note template, but I delete the previous note each day when I create a new daily noteā¦
Although this sounds bizarre and useless, this creation/ deletion helps me to realize whatās important RIGHT NOW. My template for these daily notes contains lots of embedded notes; basically, the info I MUST rememberābills to pay, receivables, vital info on current clients etc. I edit my DN template several times each week.
I add/ delete these embedded notes to and from the Daily Note template as necessary.
For daily tasks, I have a monthly note, which I simply rename every month. This is a MOC of sorts, with daily tasks, ideas, information, linksā¦
This āmonthlyā note is for stuff I need to do/ remember every single day, and new info⦠In a sense, itās a never-ending note.
Usually, itās somewhere between 500 words and 1,000 words. Itās not overly long. Once it gets beyond 1,000 words, I create new notes from some of the material.
For example, if I chat with a client, I add the info into my monthly note. When Iāve done whatever we discussed, I either create a new note for the material, or I copy/ paste the info the clientās main document. Or, I delete it, if the info hasnāt any further use.
My motto for these monthly notes, is āeverything I need, right now.ā Itās always one click away, so I know exactly what I should be doing, right nowāand whatās next. 
This strategy keeps me from feeling overwhelmed. Iāve always got what I need right now, but I can riff right in my monthly note, then hive off the riff to its own document when I need to do that.
Obsidian makes it simple to create a personal workflow, while you work.
Itās magic.
