Jenson Button feels he can do no more to convince Ron Dennis he is worthy of a new deal for next season.
Out of contract at the end of the campaign, Button currently finds himself in limbo as McLaren Group CEO Dennis has yet to make up his mind as to his driver line-up for 2015.
The suggestion is Dennis wants Fernando Alonso to spearhead what he hopes will be McLaren's return to winning ways as they welcome Honda back to F1 as power-unit supplier after a seven-year absence.
At present, Alonso is playing games with the media as he continues to throw out cryptic remarks with regard to his future.
For Button, who conjured one of his best results of the season with fourth in Russia on Sunday, he concedes he is now "past frustration" with regards waiting for Dennis to make a decision.
"I am just enjoying racing," said Button.
"It was nice the car worked at the weekend and good the team got everything out of it.
"When you come away from a weekend like that you just enjoy the moment. You don't think about external issues.
"I feel we did as well as we possibly could. I don't think I could have done any more, and I don't think anyone else could either."
As far as Button is concerned he feels he has nothing left to prove, adding: "I am not doing this for any reason to stay in F1. I am doing it for me.
"I am not thinking if I do a good job I'll get a drive. I have been in this sport too long.
"I am out there to do a good job on the day and I am enjoying it, and I really enjoy working with these guys. I feel we've a good bond and that's really helping us progress."
Suggesting it is now a case of whatever will be will be when it comes to his future, Button remarked: "I'm no longer annoyed when people keep asking me.
"I was (annoyed) at the last race, but I am more relaxed with it. It is getting so close to the end of the season, it is actually getting funny.
"But I'm not worried or scared with regard to whatever direction I go in in the future."
