Cranky is what you call someone who is irritable and sometimes unpleasant. It can also mean eccentric, strange and unorthodox. One can be both irritable, eccentric and strange all in one package. Genius comes from that place where if people are allowed to be genuine then they can do amazing things. Perhaps the cranky old guy down the street has done some amazing work because he was allowed to be authentic and living his truth. Cranky people have a heart but they only let it seen in their creative madness.
