Stop – yes you. Just stop a minute and take a deep breath. You’re going to need it, because I’m going to ask you to hold it. For at least three hours.
I’m a big believer in Confucian theory: I hear, I forget; I see, I remember; I do, I understand (metaphorically of course, we understand sensory impairments).
It’s the doing and understanding bit you need to hang onto.
