Sound advice …

… The Learning of the Wise, Bryan Caplan | EconLog | Library of Economics and Liberty. (Hat tip, Dave Lull.)

Anyone can say, "I never studied X because I wasn't convinced it would be worth my time."  If someone genuinely seeks wisdom, though, they will set a much lower bar.  Like: "I studied X because I wasn't convinced that it wasn't worth my time."  Or: "I studied X because I thought there was a 10% chance X was right."  Or: "I studied X because I was mortally afraid of overlooking whatever nuggets of truth X contains."  If you really want to understand the world, you have to value your time less and your learning more.  Study every subject that seems vaguely relevant.  If a field has a bad reputation, see for yourself whether its reputation is deserved.  And even if a field deserves its bad reputation, seek out honorable exceptions.  

The problem with specialists is that, too often, they are only specialists.
