Nico Rosberg has said that he is heading into this weekend's Russian Grand Prix knowing that his winning streak cannot last forever.
The Mercedes driver has won the last six grands prix on the trot and is leading the 2016 world championship by 36 points.
"I'm just trying to soak up and enjoy every moment. I've never had so much fun racing in my career," he told Welt am Sonntag.
1982 world champion Keke Rosberg - Nico's father - has also acknowledged the 30-year-old's extraordinary run.
"It's going really smoothly for Nico," the former Williams and McLaren driver told Auto Bild.
"In the last six months alone, he has won more than I did in my whole Formula 1 career."
However, Nico warned that the winning streak cannot last forever.
"Put it this way," said the German. "I'm certainly not looking forward to it, but I know that the day will come, because nothing is forever.
"What is important is that I am happy - the car is great and at home I have a great wife and a healthy child, and for that I feel great gratitude."
He admitted, however, that he is less happy with the overall situation in F1, with political turmoil holding up much-needed reforms for the good of the sport.
"The way the system is at the moment cannot go on," said Rosberg.
He stands firmly with the GPDA, referring to the fact that Bernie Ecclestone recently called outspoken figures in the F1 drivers' union "windbags".
"If we are called windbags, it means at least that someone is listening," said Rosberg.
"Of course this is not a compliment, but before we were not even asked for our opinion."
Practice for the Russian Grand Prix gets underway on Friday.
