I found this great thread from @system who basically explained most of what I’m saying.
I was going to write a long post about the “mind” aspect of intelligence, but I don’t think that’s necessary… I’ll just highlight:
I guess what @system meant was that the brain “bulking” stack will make you tired and consume lots of resources and is therefore not a good idea if you intend to study hard. A 2 day break should be enough to regain some vitality and motivation.
