Verstappen also explained his ambitions of winning at least 50 races throughout the remainder of his career.
The Dutchman has had a turbulent first half of the season which has seen one win – in Red Bull’s home Grand Prix – and four failures to finish.
The 21-year-old’s DNFs have been caused by a combination of his own high risk taking and Renault’s poor engine power.
Verstappen is sixth in the Drivers’ Championship but he hopes of one day getting near Lewis Hamilton’s tally of 67 race victories.
“I’m not here to win four races. I’m here to win 50 or 60,” Verstappen said.
“The victory in Austria [is a career highlight], especially in front of so many fans but also with a Red Bull car at the Red Bull Ring was something really amazing.
“We were in a triple-header so you can’t really go partying.
“I was babysitting at home for my manager’s son, so pretty standard.”
Verstappen will be without team-mate Daniel Ricciardo next season as he has decided to move to Renault.
But the youngster is happy with Red Bull’s decision to ditch Renault engines for Honda from 2019.
“If there are new parts they will, of course, go to the factory team first which is also logical but it’s a pity for us,” Verstappen said of Renault.
“Now that it’s certain that you are making the switch to Honda, that will not work in your favour, let’s put it like that. But that’s how these things work.
“I hope we will continue to develop the car well.
“We are better than [Ferrari and Mercedes] so car-wise they are the ones who need to catch up.”
