If you want to cut your learning curve in half, learn with the intention of teaching it to somebody else.
If you had to give a presentation on what you’re learning today, you would learn it differently. You would pay closer attention. You would take more detailed notes. You would ask better questions.
When I teach something, I get to learn it twice.
People often say that those who can’t do teach. But I never saw that as a negative. I always thought, wow, if I can’t do something, I can teach it, and then I can do it.
