Esteban Gutierrez believes his performances in the latter half of this season prove he deserves to be in Formula One.
After a sluggish start to his debut campaign, the Mexican racer and Sauber both found their feet after the winter break with improvements coinciding with the introduction of the new Pirelli tyres.
With Sauber performing better, Gutierrez was able to show his own pace resulting in a seventh-place in Japan.
The 22-year-old's six points meant he finished the season as the sport's top rookie.
But despite that achievement, his future remains uncertain with reports claiming he could be dropped by Sauber after just one year.
Gutierrez, though, reckons he's done enough to show that he deserves to be in F1 and hopes to fulfill his "big goals" in the sport.
"Once you get into Formula One you have to accept that it is a pretty unstable situation for most drivers," he told the official F1 website.
"Maybe you have stability for the first three months - and the rest is a roller coaster ride. But that is something that you get used to and you should not combine what is happening around you with your performance.
"The bottom line is that I have big goals in F1 and I want to achieve them. I believe that with my race performances from Singapore onwards I have proved that I have the level to be in Formula One. So I am confident for my future. God will place things where they belong.
"Careers are very often instable and you have to bear that in mind. And if you are aware of that it also helps you to learn the value of other things in life. Life is bigger than Formula One.
"For a driver Formula One is, of course, very important - for me it includes everything that I love: the sport, the technical side, the engineering side, the business and the political side - but at the same time you have your family and you have friends - you have a life and you have to give huge value to all of the things that give you the chance to say: 'I am not fully dependent on Formula One'.
"I have other things that I value, and you need to find the right balance between your F1 life and the private person that you are. My life would not collapse if F1 did not happen, but once you're here, you have to go all in!
"Between now and January I will enhance my physical training, just like every other driver will. I want to reach another level of my physical condition with my preferred training regime: cycling. This will prepare me for next season."
