I had a professor who had this philosophy. He would push us (and he was quite good at it), and he wouldn’t stop until he figured out where the edge was. Sometimes, he would push people over and he would have to ask for forgiveness. Now, when you’re in the classroom and you’re doing mental work – with the professor pushing it, that can be quite tough.
Have you ever thought about your limits? Do you know where yours is? Do you know how to push people – in a good way – past their limits? How do you do it? Where is your limit?
