"I will try not to false start again," he said. "It's compelling to stay in the blocks as long as possible. I will try to listen to the gun and be focused, because it's the 200m and there's room for mistakes."
The mistake Bolt made on the starting blocks in the 100m final, of course, was not holding back and risking giving his rivals a split-second advantage, but jumping the gun.
"It was my fault," he insisted, rejecting the suggestion that his training partner and eventual race winner, Yohan Blake, had triggered his false start by twitching in the lane beside him.
"I can't blame anybody else. I false-started.
"After the race I just thought, 'I've got to move on from this. I've got the 200m to go. I can't get stressed about this."
After the travails of last Sunday - when he ripped his shirt over his head and banged his fists in frustration against the trackside wall - Bolt was back in sangfroid mode, clowning to the trackside television cameras and playing to the gallery of the crowd.
"I'm back to my old self," he said. Which is bad news for the rest of the field in the 200m final.
