Bill Watterson, the creator of “Calvin and Hobbes”, rarely talks about his craft, but in 1990, he took the podium at Kenyon College and gave the graduating class a gift of equally remarkable insight and impact, which remains among the greatest commencement addresses of all time: https://www.themarginalian.org/2013/05/20/bill-watterson-1990-kenyon-speech/
