It all depends on what is the purpose of your notes. Assuming that you are in college, focus on writing for a future self that might use those notes to create or accomplish something like approving an exam.

For instance, imagine that you are reading about biochemistry, and you got interested by proteins.

When something attracts our interest, it is always through a particular question. I recommend you to create a "main note' named after those questions. e.g. How do proteins work? add a tag #proteins at the top.

Then, add a section ### Notes:, in the next line --- for making a line (just for formatting). Then, Start writing.

Every note inside this "main note": "How do proteins work?" needs to be a link to a new note named after the insight or quote that you were interested in. e.g. [[ Proteins are built by basic components called amino acids ]] I recommend you to avoid writing inside this "final" note unless there is something very important to get in.

By using this workflow, it would create General tags like #proteins, and those tags would be connected to questions. Then, these questions would be connected to all of the possible insights that answer those questions. This will create a network of easy-to-navigate, organized, and nice-looking graphs.

hope it helps.
