“The greater our knowledge increases the more our ignorance unfolds.” John F. Kennedy
You don’t know what you don’t know. I used to think I was relatively smart, then I began reading more and realized that there is so much I don’t know.
We will never know everything. We can’t even know everything that we think we know, let alone use science, math, and other information/data to break through to understand new answers and technologies.
As long as you remain humble, keep an open mind, and always try to learn something new, you’ll be in a good spot. Don’t talk down to others because you think your idea of “the truth” is more complete than theirs. Over time, you’ll come to realize that your truth today is only a partial truth. It’s your truth, but then there is also the other person’s truth (their perspective of the same event/situation) and the objective truth (what happened, with no thoughts/opinions of why something was said/done, without assigning intent or judgment, etc). And what really plays with your mind is when you realize that your truth today gets twisted/altered so that when you look back at the event in five, ten, or twenty years, you have yet another version of the truth.
