McIlroy returned to Carton House today needing a major improvement on his opening 74 to make the halfway cut in the Irish Open, although the world number two did not sound overly confident of doing so.
"I've got all the time in the world," said the 24-year-old, who won five times last year, including his second major title, but has struggled to reproduce such form this season. "I'm sure it will come around eventually.
"I've got two majors left this year and I want to try to get myself in contention for those. I'd love to go into the bulk of the summer playing well and at least with a little bit of confidence.
"I had a good chat with my dad and Michael Bannon (his coach) the Saturday night of the US Open and felt like we got a bit of direction from there, but it's tough when you have rounds like this or you have tournaments where you think you're getting somewhere and all of a sudden you're stopped in your tracks and you've got to re-assess everything again.
"One of the things we talked about that night is just going out with one swing thought and sticking with that, but there's been points in the season where I'll go one day and have a swing thought on the range and the next day the thought will be different.
"I drove the ball really well last year and that was a big factor in my success, because I was hitting it long and straight. This year I've got into a couple of bad habits and when you've got one miss, that's fine, but when you can miss left and right it's hard to stand up and be confident that at least one side of the hole is out of play.
"It's just a matter of keeping at it and trying to play my way out of it I guess."
McIlroy finished six and seven shots behind playing partners Thomas Bjorn and Shane Lowry respectively, with 2009 winner Lowry in a five-strong group on five under a shot behind leader Oscar Floren of Sweden.
Floren, who lost his card at the end of last season but regained it via the qualifying school, has a best finish of 25th on the European Tour this season but carded a flawless opening 66 containing four birdies and an eagle on the 13th, where he drove the green on the short par four and holed from 20ft.
