I've studied a technique called the Sanford Miesner technique that teaches you how to focus. It's mainly about daydreaming. And the technique's really about imaginary circumstances. Using your imagination to sort of daydream about stuff. It makes you emotional in a scene.
I have sympathy for young people for their growing pains but I balk when these growing pains are pushed into the foreground when you make these young people the only vehicles of life's wisdom.
