How would you take notes from a book that you don't know when or how you will use it?
I'm still new to the method, but doing some research on the zettelkasten method, I found that the zettelkasten should always be used for some project, something you are writing. But what if I'm not working on a project, but I still want to remember what I read?
If I'm learning a skill, say copywriting, for instance, when I read a book about copywriting I won't know right away which techniques I'm going to use, I won't know when or how I'm going to use the techniques described in the book, but I know I'm going to need them.
Is the zettelkasten useful for acquiring a new skill?
In case I'm reading a self-help or philosophy book for both myself and also to be capable of giving advice to others when they might need it. How would you choose what notes to take and how would make sure you would remember what you read? Would you use SRS?
For instance, how can I remember The Meditations of Marcus Aurelius?
Any help would be very much appreciated. Thank you.
