The Jags kept up the pressure on Irn-Bru First Division leaders Morton with a 1-0 win over Airdrie United as a Chris Erskine wonder goal clinched all three points for Alan Archibald's side.
It was Thistle's second consecutive one-goal win following their victory over Hamilton Accies last midweek and while the Firhill outfit have not been at their free-flowing best, O'Donnell is delighted they are still getting the points on the board.
He said: "That is two clean sheets and two 1-0 wins in a row. If we get another 14 of them I will be more than happy with that.
"We just need to make sure we are winning the games and, to be honest, we are not bothered how any more.
"It was good to win playing nice football at the start of the season but now it is more about getting the points on the board.
"If teams want to come and play us then great, if they come and sit back then fair play to them. It is getting to the business end of the season and everyone is fighting for points.
"If I'd a set plan that wasn't pretty but got us the three points every week then I'd do it.
"We try and play and full credit to Archie, he has tried to continue that after Jackie left.
"The pitches are getting harder to play on. We have got guys like Steven Lawless and Chris Erskine who are brilliant on the ball but it is bobbling up all the time.
"There are not many players who could play on a surface like that. We will keep working away and hopefully we will keep getting results."
The Diamonds win was O'Donnell's second start in-a-row after a spell on the sidelines that had him miss several key fixtures in the title race.
He put in another decent showing from his right-back berth but knows he still has plenty more in the tank.
O'Donnell said: "I don't know about me being established after Saturday, I wasn't particularly great.
"I am glad to be back playing and to get another 90 minutes.
"Performance-wise it could still be better but I just need to keep working hard and hopefully that will come.
"As long as we are getting the three points, I will take having a bad game. I could have done a bit better personally but we got the three points."
Next up for Thistle is a trip to Cowdenbeath tomorrow as they play the second of their games in hand over the Ton.
Victory in Fife would narrow the gap at the top of the table to just two points and O'Donnell is expecting a tricky tie.
He said: "I would take another 1-0. It is going to be a tough game. We were through there in the Ramsdens Cup and it was difficult. That was earlier on in the season when the pitch was a bit better, I don't know what it is like now.
"Hopefully come tomorrow we will be ready for it and we can get the three points."
