“Insanity is doing the same thing over and over again and expecting different results,”  It’s like nails on a chalkboard every time I hear it. There is a very limited context where it may be applicable, but mostly it’s used to give up trying or mock someone for failing a task. Have you never gotten better at something over time? Learned an instrument? Played a hard video game? Learned to ride a bike? It stops problem solving dead and kills motivation making it less than useless. Oh and its misattributed to Einstein like every other shitty quote

They loved to do that shit in the 90’s. It got to where if someone threw a punch you went all out because you knew everyone was getting suspended no matter what
