After taking 6 math courses this semester (abstract algebra, analisis, and odes, among others) I've reached a point where I don't even have to actively think that much when doing a proof, kind of like when you can have a normal conversation while being lost in thought.
I can just follow the definitions and develop things like if my subconscious had already traced a clear cut path for me to follow with ease, its not until after I've read it that I can fully appreciate what I have made, then immediately think "oh shit, did I really write this?"

Have I reached enlightenment? Is this something that happens to everyone eventually and then you reach a particularly hard problem that makes you jiggle your noggin like before?
