The impression is fresh for a while. What is the first thing you do?
Do you discuss it? Do you write some kind of review for yourself? Do you explore professional reviews/analyses instead to compare the perspectives? Do you give yourself some time to form an opinion? Do you do something else?
I have a notebook where I take note of all my lectures to not forget them. I usually write down remarkable passages, quotes or my thoughts. I have a little fear of being unable to remember what I have already read haha
