I'm so judgemental

Whenever I see a wrinkled middle age man dressed in casual simple clothes I always think I'm more superior than him.When I see a bald monk in oversized baggy mono chromatic overalls, I always pass off comments like 'ugh what horrible fashion sense' . To try and curb my problem, I even googled 'How to be less judgemental' but all the results were quite useless because it's all about self control and stuff... I know karma's a bitch, but right nw, I'm a bigger bitch.
