Fernando Alonso says Ferrari cannot afford to make any mistakes in the remaining races of the season despite his advantage in the points standings.
The Spaniard became the first driver to win three races in 2012 In Germany last weekend, increasing his lead in the championship to 34 points over Red Bull's Mark Webber and 44 over Sebastian Vettel.
And while Alonso admitted he is in a good position in the championship after the halfway point of the season, but says it is too easy to lose momentum if the team makes a mistake.
"I think we are in a good position in terms of points that we have achieved in the first half of the season, but we are only halfway through," said Alonso ahead of the Hungarian Grand Prix.
"There remains another 10 important races with the same possibility for everybody and the distance between the top five/top six in the championship is not impossible to recover. You just need one or two good races and you are up there.
"We need to keep the concentration, maximise what we have in our hands each weekend. Maybe it is a podium, a fifth or seventh.
"We cannot afford to make any mistakes or anything that we will regret. We need to keep some good consistency but as for championship it is way too early to think and still McLaren and Red Bull and Lotus and Mercedes - anyone is in contention at the moment."
The two-time champion said it would be a dream for him to secure his third title and emulate the late Ayrton Senna, his childhood hero.
"I think we need to wait and see. For me it is a dream in my career to win three world championships, now or in six years' time.
"The third one will be important for me, to have the same as Ayrton had, who was my idol and a reference when I was in go-karts. Three is a big number always and hopefully it will arrive."
The Spaniard said the FIA ruling on engine maps will not affect Ferrari at all, but admitted he did not know how it will impact Red Bull Racing.
"For us it doesn't change anything, we will have exactly the same car as Silverstone and Germany - for them we have no idea," he added.
