I perform much better under stress, providing its an agreeable amount of course.
Too little and I feel unchallenged, demotivated and unfocused, my mind starts wondering to god knows where because I dont even daydream (dont remember how to) and things just drag along way too slowly for my liking.
I dont know where the switch is though, I'd prefer to flick it at will.
I wish I had definitive answers for you sis
