I think that the one trait we must all strive to possess as we grow older is to always be teachable. You can never learn enough. You can never get to a point at which there is nothing left for you to learn. You can never acquire all knowledge that there be nothing left to be added on. There is always something to improve, something you could do better, something you could be better at. Life itself is nothing if not a cycle of trying to be better than we were yesterday, a cycle of learning and unlearning. And so it is imperative that you remain teachable always. It is imperative that no matter how much you learn, you always remain curious, that you are more curious than you are content with whatever knowledge you may have. It is imperative that you keep an open mind, that you always consider the likelihood of what you know not being right at all, that what you know might not be the truth. It is imperative that you are always open to other ways, to other truths. And it is even more imperative that you learn to admit when you do not know. A lot of us were raised to fear not knowing, or at the very least to fear admitting it. We were programmed to think that it is better to feign the possession of knowledge than it is to admit the lack thereof. We were programmed to feel that not knowing is a shameful thing. Well, it isn’t. Not knowing is just that: not knowing. And there’s a beauty to it. You will, in fact, not learn anything unless you first admit that you do not know. That is where all learning begins. Any chance of you doing so goes out the window the moment you convince yourself that you already know. So be careful to never pretend to be endowed with knowledge that you do not have. It is only detrimental. Be confident enough to say “I don’t know,” confident enough to walk into a room of people who know better than you do and say, “I do not know. But I am ever so willing to learn.” Learning never stops. So ensure that it is within you to keep at it.
