This is what I have found as well. Although, when starting with Obsidian, I didn’t know about the whole ‘Atomic Note’ and ‘Evergreen Note’ etc. methods so I never really tried to get that granular. Some of my notes so far are long and disorganized as I process through different topics, and then some of my notes are short and to-the-point definitions of physical or mathematical concepts that I can link to in my longer notes.
Don’t have it all figured out yet but it is fun to see all the links starting to form over time. I am sure it will grow very quickly when classes start up this Fall.
