Think about it.
Have you ever taught someone something? Did you feel pretty good about what you taught them afterward? Did you want to teach it again, and again?
Now, have you ever just had someone try to teach YOU something…. and just talked, and talked, and talked….
Did you learn anything?
Teaching someone something can be so rewarding, but you need to put yourself into their shoes… from THEIR perspective… try to get them to teach it back to you, rather than you just talk.
You'll be amazed at how much they learn.
