Charlie Munger is essentially the right-hand man to popular businessman Warren Buffett.
Munger had this to say about our ability to change our beliefs on certain preconceived ideas:
“We all are learning, modifying, or destroying ideas all the time. Rapid destruction of your ideas when the time is right is one of the most valuable qualities you can acquire. You must force yourself to consider arguments on the other side.”
Some people would rather convince themselves they’re right about something rather than listen to an argument from another side.
That also applies to doing things the way they’ve always done rather than considering a new idea or improvement that would better fit the circumstances in the present.
The need to be right should never overshadow the truth.
That’s why disregarding old ideas that are no longer effective or true is essential when it comes to moving forward in any area of life.
