  2. Some Reflections on a Career in Computer Science During Its Formative Years • “The best way to predict the future is to go out and create it” • And have a lot of fun doing it • “One man’s ceiling is another man’s floor” • It’s a big world, with lot’s of specialization • “Its déjà vu, all over again” • Expect to revisit topics many times before they stick • Details (and implementations) matter, often as much as ideas • Especially early on to build credibility (in the longer run they are often lost in translation/transition)
