PERSPECTIVE – “It’s bad to have an opinion you’re proud of if you can’t state the arguments for the other side better than your opponents. This is a great mental discipline.” – This mental exercise comes from Charlie’s early training in law, where it is an advantage to be able to argue both sides of a case. Knowing the other side’s arguments, its possible points of attack, allows one to prepare counterattacks long before a case gets into the courtroom. The most interesting thing about this mental exercise is that after learning the other side’s arguments we just might discover that they are right and we were wrong. Which is probably why so few people take Charlie’s advice on this. -Tao of Charlie Munger by David Clark
