If you think you know something that is important to your business’s success, then teach it to others.
Teaching is a great way of learning and taking your understanding to the next level. When you teach, you really have to know your stuff, and be able to express it well.
Don’t wait until you are perfect. The idea is that you won’t be UNTIL you teach, and teach again.
As a leader, teaching is an important part of your job – for the advancement of your team, and your own.
