There are a lot of things that make a good teacher. I strongly believe that teaching is a skill that need desire, improvement, humility and adaptability. A teacher with patience, strong knowledge and can explain to 'everyone' by combining the technical and/or informal explanations. He/she needs to understand that different people learn in different ways, so the approaches (if possible) have to be distinct. He/she has to be well prepared and comes with a strong desire to really teach and make a difference in people's lives. Essentially, being humble and not self-centered, in order to teach each student in a fair and efficient way. Teachers are extremely important, especially when they know how to teach. Don't underestimate your ability to change drastically people's lives for good.
