Scott admitted he could have easily given up his chances after the debacle on the eighth, where he hit two separate bunkers and also found a lake.
"Maybe I wouldn't have bounced back in the past,'' he said.
"But my whole mindset for the game is really good at the moment and I'm very content with everything I'm doing.
"I am certainly a mature golfer these days. I have a lot of experience and it's happened to me a million times.
"I know I had 10 holes to play which means 10 opportunities to look at.
"When you're playing well you can't let a hiccup affect you because if I did we'd have a knock on affect and I'd end up at three under.
"Then I've got nothing out of the week and feel like I'm not playing well when I really am.''
While his lead is gone, the 31-year-old Queenslander remained confident he could power forward over the weekend and pick up a second WGC title.
"I'm right where I want to be,'' he said.
"I've set myself up for a good look over the weekend but I'm just going to have to be really sharp, because there's no doubt there are going to be low scores out there.
"I'm going to need to shoot in the 60s somewhere.''
Jason Day rebounded from a one over par round on the opening day with a five-under par 67, leaving him as the next best Australian at four under in a tie for 21st.
Greg Chalmers (-3, T24), John Senden (-1, T34), Aaron Baddeley (-1, T34), Marcus Fraser (E, T46) and Geoff Ogilvy (+2, T58) have plenty of work to do on the weekend.
Tiger Woods shot a five under par 67 to move to five under and a tie for 15th.
