What is the *single* best piece of career advice you have ever received?
"Focus on the students, since graduating great students means you'll produce great research, while focusing on the research may or may not produce great students." by David Notkin (1955-2013) (my academic father) who passed it along from Nico Habermann (1932-1993) (my academic grandfather). Such advice can be generalized to other places, e.g., focus on (care about) people. Such advice is related to an old Chinese Proverb “授人以鱼,三餐之需;授人以渔,终生之用” whose English version is "If you give a man a fish you feed him for a day. If you teach a man to fish you feed him for a lifetime."
