I use a software named notion (which is a great app by the way,Check it out👀).I used in three ways generally
I have built a system to get everything I read,watch and comments on it along with quick random thoughts on it.So that I can categorize and get it when I want.I also allows me to sit on the content and add additional info to it.
I have built another system in it to input my thoughts, emotions,memories, aspirations,habits and other things into it like a journal where I can check whenever I want and work on it.I also publish some insights developed from it in the form of creative outlets such as psenoumous social handles
I have another system to track my tasks,work and other stuff
The best thing in this is that I can link the above three things.
If we want to know any particular detail,just let me know. would love to help🤝
My starting point for notion as second brain is the link,Check this if you haven't already
