Mark Webber says he cannot rely on just delivering consistent results this season - and that he must win races if he is to fight for the championship.
The Red Bull Racing driver is one of only three drivers who have scored points in every race this season, with his four fourth-place finishes currently helping him to third spot in the drivers' championship standings.
But with the season being so tight, Webber knows that he will need to start racking up better results if he is to overhaul his rivals.
"It was frustrating to finish in Lewis' [Hamilton] gearbox in Melbourne, in Malaysia and in China as well," said Webber ahead of the Spanish GP.
"It is always nice to get points at each race, and you could not have thought that would have been the case because it has been so up and down.
"I've been consistent, and I realise I need to keep doing that - but I also need to win as well. When the opportunity isn't there to do that you need to finish, but 25 points makes a big difference - although if you are in the fence that makes a big difference as well."
Webber also thinks that the shape of F1 is very different this year, because it is so unpredictable.
"I think it is a new situation right now," he said. "Who is going to be on pole this weekend? It could be McLaren, Red Bull, Mercedes, Renault [Lotus] - it could be Ferrari. So it is very unusual in that sense.
"It is probably less so as we get a bit of information in P2, but before the weekend we are not really sure who is going to do what - and Monaco is going to be unknown again. We don't know until we get there."
