Shane Watson admits he has to learn to cope with the pressure as he looks to make the most of his chance to shine for Australia in the Ashes.
The 28-year-old all-rounder was surprisingly called on to open the batting in the third Test against England at Edgbaston, and he made an impressive start with 62 runs on the first day.
However, his dismissal sparked an Australian collapse when he fell to the first ball of day two from Graham Onions, and he admits nerves got the better of him.
"I didn't sleep too well, going over in my mind what I was going to do to make a really big score," he said.
"It wasn't a great ball that got me out - I just stuffed up - but I will learn from it."
He added: "I was very nervous. Opening the batting did increase the pressure on me, but it was a great challenge."
Watson has struggled with injuries throughout his career and, after playing just nine Tests in four years, he is doing all he can to make sure he does not pass up the opportunity to establish himself in this series.
"My technique was maybe a bit complicated so I have worked hard at simplifying it," he said.
"My career has never really gone to plan but I am going to do everything I can to take this chance."
