Good teachers – the wise ones – learn from their students. When you share your wisdom with others, it expands your own knowledge. That’s because you have to comprehend something on a higher level to be able to explain it to someone else. And, when you’re teaching you get asked great questions. Sometimes really challenging questions that force you to deepen your understanding to be able to answer them. You don’t have to be an expert to have something worth sharing. Everyone can offer something, and learn something.
