Langer, at the end of his four-year contract, will soon meet with Cricket Australia bosses.
Fresh from a 4-0 Ashes triumph and capturing Australia's first World Twenty20 World Cup, Langer says he's content in the lead-up to the crucial talks.
"I'm never edgy (about the future)," he told SEN Radio on Wednesday.
"Before the World Cup and before the Ashes, we've never ever been better prepared so it's not a coincidence ... that we've had the success that we've had.
"Whatever happens from now on, we can all be incredibly proud of this little period.
"We had two missions: to win the World Cup and to win the Ashes.
"To do that in such a short period is a monumental effort and we're all really satisfied with that, we're all really happy about that, we're all really, really proud of that.
"I sit here at the moment feeling really content with the last two series."
Langer coached both triumphs amid speculation about his future, acknowledging he had lightened his renowned intensity which had upset some players.
But Langer said he was always comfortable with his agreement with CA hierarchy to delay any discussions about his job until after the Ashes.
"People don't seem to believe this but the absolute truth is before the World Cup and the Ashes we all committed to the end of the Ashes to sit down and have some conversations," he said.
"It has been four really big years and it's an all-encompassing job and it's a tough gig … that's just the truth.
"We all said that we would sit down after the Ashes so, in the next little bit, I'm sure those conversations will start to be had.
"There's plenty to be spoken about."
