These pearls of wisdom are no less than PG's essays. What I find most impressive about his wisdom is that it had withstood the test of time....it's not just about finding the next big idea and executing it when you are 20/30 something and then do what? It goes much more deeper than that. It is about how to maintain genuine interest in programming, over a period, measured in decades(spanning all different type of envmts) and not years/months...To me that is the ultimate measure of success(for a hacker atleast).
