Lewis Hamilton leads Felipe Massa in the F1 title race by one point
Lewis Hamilton believes he is in better shape for the Formula One world title showdown this year than he was in 2007.
The Englishman lost out in his debut season last year despite a healthy lead going into the final races.
"I'm definitely in a different mental state than last year," said Hamilton ahead of Sunday's Singapore Grand Prix.
"Last year I was a bit tense and nervous in the last few races. This year I don't have any of that. I understand what I need to do."
Hamilton is one point ahead of title rival Felipe Massa of Ferrari with four races to go.
He would be seven points ahead had it not been for the penalty that deprived him of victory in the Belgian Grand Prix earlier this month.
McLaren failed to overturn that penalty, for gaining an advantage by going off the track while racing Ferrari's Kimi Raikkonen, at a hearing on Monday but Hamilton said he was not letting that prey on his mind.
Massa says Hamilton's Spa penalty would not devalue a title won by him
"All that is in the past," he said. "Now we're focusing on the next few races. I feel I've got to work hard but I don't feel any negatives about anything else."
Massa said he was not dwelling on the consequences of McLaren's failed appeal and rejected suggestions the penalty would devalue the title if he won it.
"If I win the championship by one point, I am the winner. It doesn't change anything," said the Brazilian.
"We don't need to think about that. We need to think about the championship, which is open.
"When you look at the rules, it was pretty clear the appeal was going to be difficult for them, but you never know until the result comes out.
"I think the result was pretty fair. I am not thinking about that, I am thinking about the race, which is much more important than all the political media pushing."
We have the best car for both conditions so whether dry or wet, I'm not bothered
The new Singapore street circuit will host F1's first night race.
The drivers, who are trying to keep their bodyclocks on European time in Singapore because the race starts at 2000 local time, have been exploring the track on bikes, scooters and on foot since their arrival.
They get their first taste of it in practice on Friday and Hamilton believes Saturday's qualifying session could be crucial in deciding the outcome of the race on Sunday because of a lack of overtaking opportunities.
"Overtaking is going to be very tricky, as it is at all street circuits," said Hamilton.
"There'll be less overtaking than at the other circuits we have. It's going to come down to qualifying."
Hamilton promised to "attack" this weekend.
The Singapore track winds through the centre of the famous city
"I think we can approach these next races with the same confidence we did the last because we have got a great package, we have done a great job to prepare the car," he added.
"I've got great confidence in the car, the reliability is good. I just need to take the right steps over the weekend, but I really feel confident.
"These last four races are like starting from scratch. There's only one point in it and I've got to look at this race the same as I have over the last few races and really try and attack this weekend and get points."
The 3.15-mile track promises to be a test for the drivers with thunderstorms forecast for Saturday's qualifying and Sunday's race day, making the unknown scenario of racing under floodlights in the wet a real possibility.
If it rains, Hamilton will be many people's favourite to win given his supreme skills in the wet, but the McLaren driver is hoping for dry weather.
