I worked with creative people who were very demanding of me and they helped me reach performances that I never could have gotten on my own without being pushed and having trust in them. And so I know the best way to get the best performance of an actor and that's not to coddle them or to baby them. It's to help them it's to push them.
One of the most predictable things in life is there will be change. You are better off if you can have a say in the change. But you are ignorant or naive if you don't think there will be change whether you want it to or not.
