Jenson Button says he has no interest in racing in any other categories outside Formula 1, despite his ongoing contractual stalemate with McLaren.
The 2009 F1 world champion has repeatedly expressed his desire to stay with McLaren after his current deal expires at the end of this season, but the team has remained non-committal on whether it will retain Button and rookie team-mate Kevin Magnussen next season.
The lack of progress on a new deal for Button has prompted questions over whether he might pursue a career outside F1 in 2015, but the Brit says he has no desire to be anywhere else.
"Right now, my interest is to race in F1," Button said.
"You have a tough day and it hurts like hell because you want to be competitive and fighting, but then you have a reasonable qualifying and you are back on track.
"You want to race forever. In F1 the emotions are all over the place - it is highs, it is lows.
"I have lived my life like that for a long time and I want to continue my life like that.
"I am young and fast and enjoy what I do for a living, and I don't want that to change."
McLaren racing director Eric Boullier told AUTOSPORT the Woking-based team was "happy with its driver line-up at the moment".
"Jenson knows the important thing is to score as many points as he can," Boullier added.
"He doesn't have to prove anything as he is a world champion and has won many races for McLaren.
"I think we need to be realistic as well, because in one, two, three years we may need to refresh our driver line-up and obviously we will be seeking the best drivers at that moment in time."
