The best way to learn is to teach. As a teacher, you always get that student that asks, “why?” so you need to have a pretty good idea of all the answers. That forces you to really think and consider all the possibilities.

As a student you can fake knowledge with a couple of well placed facts. But a good teacher knows they need to constantly find better and clearer ways of presenting ideas and have to be able to meet any questions or disagreements that arise.

Blogging is a great way to teach, and giving public presentations is even better. Then you can’t edit endlessly. When it is live you have to make sure you prepared far in advance. In addition, you have all those extra presentation elements that come into play.

Start giving regular speeches about your favorite topic and watch your knowledge soar.
