Cynicism 

"…To all the people watching, I can never thank you enough for your kindness to me and I’ll think about it for the rest of my life. All I ask of you is one thing: please don’t be cynical. I hate cynicism — it’s my least favorite quality and it doesn’t lead anywhere. Nobody in life gets exactly what they thought they were going to get. But if you work really hard and you’re kind, amazing things will happen… amazing things will happen."  - Conan O’Brien
