Madness is a very offensive term when you accuse someone of being mad but if a friend of yours call you mad, you feel complimented. Twisted and complicated as it may sound, we are all mad on some level.
Your madness could become your greatest ally, if one makes peace with it, or it may suck you into a vortex of dark pit, if you try to resist it.
Take example of this picture, To me it is a picture of a man wearing a large hat and a scarf. His head is tilted back, he is standing on some cables like an acrobat and he is playing a musical instrument. But in reality it is just some part of a machinery.
cheers... ;)
PS: When the lecture is really boring an the Professor's voice just seems like grating on your nerves, Try this trick of imaging things on his lecture slides.
PPS: If you followed my advice and are being kicked out of class for showing a goofy smile during lecture, then I apologize in advance ;)
