No man is easier to deceive than one who is smugly confident of his own sophistication.
So many of us want to be important very badly. When we start to believe we’re important, intelligent, or sophisticated we very often let this consume our decency and humility.
We become self-convinced of our own superiority and hence less patient and more condescending to people around us.
That attitude, when it remains unchecked, will set you up for crushing defeat and shame. When something incorrect slips into your “knowledge circle” and you carry yourself with that same smug arrogance, but you turn out to be wrong.
At that moment, you lose all credibility and trust. Now you’re resented by everyone and we all know you’re wrong as well.
Be careful of how you carry the knowledge you learn and operate with humility.
