Think he's too seasoned at this point.
Besides - when you're good at what you do you shouldnt be nervous.
Well, you already admitted to only trading a tiny account, so I'm not sure you should have a strong opinion in that matter.
There's many top performers who still got nerves. And I'd say that's in fields that have far more certainty than trading.
I'm trying to make this as a full-time trader with a limited account, so I think some nervousness is allowed.
Besides - when I speak of nervousness I'm mostly referring to being uncertain. Not flat out shaking.
