Williams rookie George Russell says that talent alone hasn't sustained Lewis Hamilton at the top of F1's hierarchy, with a work ethic and motivation also playing a big part in the Mercedes driver's success.
As a protégé of the German manufacturer, Russell had the opportunity last year to closely watch the five-time world champion at work, and take away a "refreshing" observation.
"There's a number of different perceptions of how Lewis's commitment is over the course of the year," Russell told Autosport.
"He's got a number of different activities he does and he's an extremely talented driver but when he comes to the track he will work his arse off to maximise everything - pushing the team in such an amazing direction, really motivating everybody.
"He's worked really hard at it, so that was kind of refreshing for me, that a guy like him isn't just relying on his talent and it just comes to him, he's out there working for it.
"I think that's something he's probably improved on as he's got older," added the reigning F2 champion.
"He can't go out and rely on speed because if the car's not quite working, you need to be able to push the team forward in the right direction.
"I'm convinced that that's what he's been doing over the last few years."
On the eve of his maiden season of Grand Prix racing, Russell knows that performing successfully at the highest level requires a blend of qualities that go well beyond a driver's simple natural ability.
"I'm trying to excel in all areas," said the 20-year-old.
"If you want to become world champion you cannot just rely on your speed on the track, or focus on that.
"There's so much more to F1, you're representing brands and have a number of sponsors who are helping you go racing.
"You need to provide something back for them so they help us develop the car further. It's a whole package and it's something Lewis is doing really well at the moment."
