1. Does "I simply remember the next one" mean he only sticks to the present?
2. Does "you cannot truly know what will happen next" mean "you should act as if you didn't know what will happen next"? "You should immerse in the present moment..?"

"I only remember the next one" simply means that when you are in a play, it's only important to know what you're going to say next. Even though it doesn't work like this, it would be absolutely fine if, as soon as a line has finished coming out of your mouth, you just forget it.
