Clarke maintains, despite his big hundred in the drawn third Test at Emirates Old Trafford, he did not perform as well as he should last time round.
His captaincy, however, drew praise from many - even on the way to Australia's 3-0 defeat.
With the first Test of a second back-to-back series only 10 days away, Clarke was speaking on Monday in Sydney at the launch of his 'Ashes Diary' chronicle of the first instalment.
By consensus, he is the antithesis as a tactician of his more conservative opposite number Alastair Cook.
The latter's name was not mentioned, but contrasts and comparisons were obvious.
Asked if he may tone down some of his methods - inventive field-settings, bowling changes et al - Clarke said: "I hope not - because if that's the case, they've got the wrong man as captain.
"I don't have that negativity in me. It's about trying to win games of cricket.
"I understand there are times and places to put fielders on the boundary and be a little defensive throughout the game.
"But that doesn't mean my mind-set changes.
"I will be trying to win as many games as possible - and sometimes you risk losing."
Clarke accepts it goes with the territory for an international captain to have critics as well as admirers.
While Cook has had plenty of public advice from record-breaking former Australia leg-spinner Shane Warne, no fan of the Englishman's "boring" leadership, Clarke too knows he cannot please everyone.
"The criticism comes with playing sport at the highest level, and it certainly comes with being captain of the Australia cricket team," he said.
"I don't know too many past captains that haven't copped a bit of criticism.
"I'm sure there is a lot more for me to come."
That does not mean he will be changing, although after making 381 runs at an average of almost 48 in five Tests so far against England this year, he believes he can do better as a batsman.
"The only way I know how to do it is to be extremely positive," he said.
"I continue to say first and foremost the captain needs to stand up and perform well.
"I didn't feel I performed as well personally, so that is my goal this (Australian) summer - to lead by example."
Australia were beset on their Ashes tour by several mitigating factors, not least the sacking of coach Mickey Arthur only weeks before the start of the series.
Clarke was a close ally of Arthur's but has long known his successor Darren Lehmann, initially as a team-mate, very well too.
In the circumstances, Clarke believes Australia could have struggled even more.
"There were a number of incidents on and off the field, where this team could have broken down and fallen apart and lost the series 5-0," he said.
"But I think everything that happened to the team brought us closer.
"When you see us on the field you can't fake that. We have shown that in the way we are playing.
"We know how hard a job it's going to be to get back to being the number one Test team in the world, but everyone in my opinion can play a huge part in us getting back there."
Clarke knows his team will be determined, as well as capable, as they seek to stop England winning the urn for a fourth successive time.
"It was so devastating that we couldn't get a win," he said.
"I wanted to win so badly for the guys, for the work they put in.
"I think if we had [won] the first Test, the (series) result might have completely different."
The 32-year-old missed both last summer's Champions Trophy in England, and then Australia's one-day series in India, because of a chronic back problem.
He has been back in action, and form, for New South Wales in Australia's early domestic season but - along with fast bowlers Ryan Harris and Peter Siddle - will sit out this week's Sheffield Shield programme, before the first Test against England in Brisbane on November 21.
With Australia due to name a 12 or 13-man squad on Tuesday for the Gabba, he added: "My body is 100 percent now, and I feel fully fit.
"It was always the plan to play two of the three Shield games, like I did last summer, before South Africa.
"Having the time off now allows me to focus on the preparation for the first Test."
