The Brazilian has been buoyed by a strong finish last season which guaranteed a one-year contract extension with the Italian team, reports Xinhua.
"I want to be competitive in 2013, start winning again and challenge for the championship," Massa said.
"I have done it before and it's something that you don't forget how to do."
The 31-year-old scored just 23 points in the first half of last season before a series of impressive results catapulted him to seventh in the drivers' standings with 122 points.
He is already preparing for the first race of the new season in Melbourne March 17 with a refreshed outlook.
"When I step into the car I enjoy myself," Massa said.
"When this happens I am able to perform better. I think I could have my best year ahead of me."
