With his team currently seven points from safety, the 66-year-old admits keeping his side in the Premier League would be his best achievement
Redknapp's men currently sit second from bottom in the Premier League and are seven points adrift of safety ahead of their clash with Fulham on Monday.
"I want to do well for QPR, the club and the fans, but I don't worry about getting the sack or about how I'm going to make a living. Whatever happens, it's not going to change my life now," he told reporters.
"Don't get me wrong, your pride's at stake and I still get knocked for six when we lose games we could have won, like our last match as Aston Villa. I still have nothing much else on my mind other than trying to think how we can get out of this situation.
"I am always thinking about the team, the way we have to approach games. Without a doubt, keeping Rangers in the Premier League would top taking Tottenham into the Champions League."
The former Spurs boss also criticised the dismissal of managers involved in the relegation battle following the sackings of Nigel Adkins at Southampton, Brian McDermott at Reading and Martin O'Neill at Sunderland.
"Managers in the Championship must wonder if winning promotion is worth it in the long run. If they don't do well straight away in the Premier League, there is a real chance they will lose their jobs," he continued.
"You are only a few games away from being under pressure. It's crazy. These owners make a big success of their businesses, they don't understand why their football team is not top of the league.
"You didn't need to be a genius to predict Reading would be near the bottom and that Wigan would be down there again."
