McLaren Honda's Jenson Button insists he is not thinking about the future and is just enjoying "living in the moment".

Button recently confirmed that his seat at McLaren is far from guaranteed for 2016, while adding "there are always options everywhere", and ahead of this weekend's Hungarian Grand Prix, he refused to be drawn when asked if he is contemplating next year.

"I can't say yes to that question because then everyone asks me the question, 'what are you going to do next year? - are you going to be in F1 or are you not going to be in F1?' So for me, I think early last year I decided to really live in the moment and not think too much about the future because none of us know what is going to happen tomorrow," said the 2009 F1 World Champion.

"Living in the moment to improve the future is fair enough, but I don't want to look into the future and think we will be winning races from race one next year. It is about getting your head down and making the difference now. Then you see what happens in the future," added the Briton, who has been linked with a return to Williams, should Valtteri Bottas go to Ferrari and should McLaren drop him.

Button also insisted that despite all the difficulties this season at McLaren Honda, he has - and is - enjoying still being in F1.

"I am still driving a Formula 1 car for a living. It is not a bad job!" he continued. "I'd rather be winning, but this year is about working flat-out to improve.

"You have always got Fernando [Alonso] - a very competitive team-mate to judge yourself against, which is always quite fun in practice, qualifying and the race, but also to see the improvements that are made through team effort and through your opinion and your feeling of the car and engine, is also a great feeling."

Button is also hopeful he can end his run of three successive DNFs in Hungary this Sunday and get in the points again, like he managed in Monaco.

"It should suit us much more in terms of layout of the circuit," he explained. "We have some parts that will help the weaknesses that we have in certain speed corners. You would have to say we are hoping for points - the last time I scored points was Monaco and it was the last time I finished a race [too]. I suppose there is a pretty good possibility of scoring points here."
