Regardless of how talented, skilled or successful you are, there is always room for growth and you can always learn something from others.
Everyone we meet teaches us something, be it from a professional level or a personal level, we are always learning. Or at least we should be.
We are all here to learn from each other and the best teachers in life are the best students. These are the individuals that actively listen and observe, even while they are teaching. They are constantly self-evaluating and wanting to improve. They are curious. They crave learning because they understand to be a good teacher, you must be an be a better student. Some of our best and most valued lessons are learned from those that we don't want to emulate. Others teach us by giving us an 'ah-ha moment'. Those moments when we realize that we didn't even know what we didn't know. Some people teach us through their unique and authentic way of being themselves and we become inspired by their authenticity. As human beings we are influenced and taught by everyone we encounter, even if we are not consciously aware of the lesson.
There are leaders who are naturally skilled at teaching and others who are not. You must be curious to be an outstanding leader. Being curious gives us the ability to be open to new teachings, new ways and new ideas. Part of what is wrong in many industries is the unwillingness of leaders to bring in different and disruptive thinking to create new ways for the organizations that they represent. The best leaders are those that love to learn and there are certainly ones that are doing it right by cultivating curious and inquisitive teams. The lesson? Stay curious and encourage it in those around you.
