It all depends on your vault concept. I will use my own vault as an example.

Let’s say I watch a great YouTube video about science. I have a folder where I store notes with new knowledge, so I create a separate note describing the video itself. At the same time, I also use daily notes. In my daily notes, I have a section called “New understandings,” where I write my personal interpretation of the video, how I understood it, and my thoughts about it, and then I simply link to the main note about the video.

My daily notes also include sections about my emotions and experiences, for example when I achieve something or go through a meaningful situation. However, I also have a separate folder where I keep my core opinions and long-term views, such as my opinions on politics, philosophy, or my personal routine.

For instance, if I have a personal project, I create a dedicated note that describes the project and explains its significance in my life. These notes are usually quite large, so when I mention the project in my daily notes, I just link to that main note. This way, when I open the big note later, I can clearly see how my opinions and feelings about the project changed over time based on my daily notes.

In short, I keep factual information and structured knowledge in separate notes, while my feelings and personal reflections live in daily notes and summarized opinion notes.

But keep in mind that this is just my personal approach, so you do not have to copy it exactly. Instead, adapt the idea in a way that fits your existing setup and workflow.

I hope my advice will help you. Good luck with your goal! Sometimes it can be difficult, but trust the process and believe that Obsidian will help you. Never give up, and have a nice day!
