Black opened his speech with this self-deprecating confession that doubled as one of the most honest moments you'll find in a commencement address. While most speakers present themselves as authorities dispensing hard-won wisdom, Black cheerfully admitted he had no particular qualifications for giving life advice. The humor carried a real lesson about intellectual honesty and humility. Black's career had indeed been somewhat accidental — from comedy troupe member to unexpected movie star in films like School of Rock and Kung Fu Panda. His willingness to acknowledge the role of luck and good fortune in his success was more honest than the typical commencement narrative of hard work and determination leading inevitably to achievement. By not taking himself seriously, Black paradoxically made his actual advice more credible. When he told graduates to enjoy life, take risks, and not worry too much about having a perfect plan, the words carried weight precisely because they came from someone who wasn't pretending to have figured everything out.
