The strength of your convictions doesn’t determine the accuracy of your beliefs. Confidence isn’t a measure of truth. The accuracy of the information that leads you to your convictions is what matters.
A balance between confidence and humility is important. Confidence without humility is hubris. And humility without confidence can cause us to be easily lead astray. That’s the value of having convictions—to keep us from being mislead. But if our convictions are based on false beliefs, we’re already off course.
Our education is never complete. Remain a lifelong learner. There’s more information available than you’re ever going to need. The challenge is to find relevant and accurate information.
