Nah, Ricky, I'm not with you on this at all. When he got to the "preparing" touches, after Barry "slipped" (come on, mate. He deserves some credit, no?) he was already in the deadly mental swamp. Thinking, pondering, planning. He''l continue to struggle till he finds the resources to overcome that basic frailty.
I agree with qs on stuff to do: it's no guarantee, but surely a gradual gaining of confidence, through routine exercise and the like, would help him there. (if I'm right that the main issue is mental, that is).
