The perspective of spending 1 or 2 hours playing videogames or watching entertainment (movies, series) became terribly boring to me. I can only think of that as a loss of time: I wouldn't be a better person at the end of it.
Being able to better smash buttons, faster, at the right timing -- watching a story unfold on screen -- these used to be a great source of joy "before". But today, it seems all so dull; my intellect or my body doesn't get any better by doing that. Instead, reading whatever book on ML or even on an obscure programming language or technique, or spending time at the gym, or listening to a lecture on math or physics, sound so much more appealing to me.
I cannot spend time anymore just sitting, it literally upsets me. Anybody feeling the same?
