Ed Cowan has sworn not to fall into the trap of complacency following his breakthrough Test ton in Brisbane.
The Australian opener admits preparing for the second Test against South Africa in Adelaide as a century-maker has changed his mindset, but says he can't afford to relax.
Cowan remembers all too well the moments of self-doubt he's experienced as a cricketer.
In his own words, he never sat at home "wallowing in a glass of whiskey" contemplating whether he had it in him to be a Test opener.
But by the same token he's not about to drown himself in champagne after a maiden century.
"Its nice to come in off the back of some runs but at the same time all that means is that I know I'm playing well," Cowan said.
"Its a nice affirmation in that sense but it's a new week, new conditions, it's the second Test of the biggest series I've played in so far, so there's no complacency.
"It's time to now cash in on some good form rather than search for it."
Cowan had struggled for Sheffield Shield runs leading into this series, but said he prepared for the Gabba opener determined to not let it affect him.
"I wanted to spend time in the middle and I was desperately hoping to score hundreds, but I kept saying, `just judge me on what happens in Test cricket'," he said.
Cowan couldn't escape the odd negative thought creeping into his mind but has managed to eradicate them the best possible way.
"They're only fleeting thoughts. I'm not sitting at home wallowing in a glass of whiskey. They're just moments I've (asked), 'am I doing this the right way?'", he said.
"To have that affirmation (of a century), you know you're the best judge of your own performance.
"Batting is about rhythm and feeling and after a while you get a pretty good indicator of how you're going so I always felt like I was close."
Cowan said Morne Morkel - who would have had his wicket early if not for a front foot no-ball, - was South Africa's best bowler in Brisbane, but he was equally wary of firebrand Dale Steyn heading into Adelaide.
