Da importância de cortar o buchetti

Do livro "A Wealth of Common Sense" do Ben Carlson:
"Confucius once said, “Real knowledge is to know the extent of one’s ignorance.” While most investing books focus exclusively on the steps you need to take to get rich in a hurry, I’m going to start off by going the other way with some negative knowledge. Negative knowledge is the process of first looking at what does not work to eventually come to the realization of what does. This process of elimination may seem like a minor distinction and a backwards way of looking at the world, but once investors are able to negate bad behavior, all that’s left over are improvements and better decisions. Negative knowledge can be much more powerful than positive knowledge because cutting down on unforced errors is so often the most important determining factor of portfolio results. It’s impossible to quantify opportunity costs, but most of the best investment decisions you will ever make will be the opportunities you turn down."
