So

When I was younger, I was cocky and arrogant, because I felt I knew just about everything I needed to know.

When I realized I didn’t know much, I became more withdrawn and just paid attention to the cocky and arrogant people around me, because they seemed to know shit.

Then I realized that noone really knows shit, or at least not as much as they think they do, so then I became cocky and arrogant once more.
