I think, this is the most important question. More so when we are inundated with loads of information.
Answering this question with answers like
I want to remember and use the information to pass my exams/test
I want to just read for fun for entertainment as a feel good /pampering time
I want to remember and hence I will highlight, take notes, summarize and write an article or implement the tips on my daily life.
Each answer helps me channelize my energy differently. In case I don't remember what I read for entertainment purposes, I don't need to beat myself up saying
"Oh my memory is bad."
