The former Blackburn midfielder has been in great form in the last few games, culminating in his man-of-the-match performance against Crewe on Monday.
But things have not been going for Wednesday up until the last two games where successive wins and the end of a much-publicised goal drought have seen Paul Sturrock's men climb out of the relegation zone.
O'Brien is not complacent though, he knows that Wednesday have to keep playing like they did against Burnley and Crewe to make sure they are safe in time before the last few weeks of the season.
"Yeah definitely," he told Footymad. "We have always said that from the first game of the season that we have enough quality to keep us in the league but we can’t just think about just avoiding relegation because we have to push on and get as many points as we can to finish as high as possible.
"But hopefully we can turn our position around and over the New Year period we look to be doing that."
Personally things have been going well for the Scot but he is more focussed on putting praise on the team than his own individual showings.
He added: "At the end of the day it’s a team effort and the team as a whole have improved their performances in the last few games but I have always said that if I could get a good run of games under my belt, then hopefully my own personal performances can improve and get a little bit of consistency."
Wednesday yesterday signed Peter Gilbert from Leicester City for a nominal fee after the left-back impressed during a loan spell and Nicky Weaver will continue to play for The Owls until at least the Foxes game in two weeks - but he will not be eligible for the FA Cup clash with Charlton this Saturday.
