One of the biggest skills that you can have in your toolbox is patience. When teaching we're (supposed to be) the subject matter experts in what we're transferring to a new mind. Because we've done what we're teaching for so long, we may run into a "let me do it for you" thought process at times. It really doesn't teach anything. When I teach, I use various methods. I take it all the way down to the "for dummies" version without insulting their intelligence and give it to them in a wash, rinse, and repeat manner. Show them how to do something, explain why it was done like that, and allow them to do it until they understand how and why, then we go to the next block. After the next block, we go back to the first one to check the retention and do the same for all.
