Lewis Hamilton insisted this week that he has no regrets about his decision to leave McLaren and move to Mercedes in 2013, although he admits that he faces a big challenge in the coming few years if he's to succeed in putting Mercedes back on top in F1.
"I really do believe that I made a good choice," the 28-year-old told Sky News
this week. "I've had a great career at McLaren, a fantastic team full of great people there.
"This is just a new chapter for me, a new experience where I've got to use all the communications skills and all the skills I know and have learned over the years and put them into something fresh and new," he continued, before acknowledging the enormity of the task that now confronted him and his new team.
"Obviously the car towards the end of the year  was a good second off the McLaren and off the guys in the Red Bulls, so I know we've got that to climb and more on top of that because people will have developed probably a good second and a half or so through this winter," he admitted.
"This is more a marathon for me than a sprint, I'm here for the long haul - it's a long journey up ahead," he insisted with evident determination. "We can all do better, all of us. It's about us trying to extract more out of each other."
So where will the former world champion start in his formidable task to put the once dominant marque back on top in F1 Grand Prix racing?
"I know we've got a lot of work to do, but I've seen a great spirit here. The guys are working flat out, and they look like they're hungry - and so am I!" he said with a smile. "So we've definitely got something straight in common, and I'm excited about that.
"I knew that we've got a lot of work ahead of us and I'm still very realistic about that as well," he continued. "We've just got to take it one day at a time. We haven't even got to the first test, so we don't even know if the car will make its first ten laps! We don't know anything at the moment. It's all a bit unknown."
It's not until that first four-day test - which begins on February 5 at the Spanish circuit of Jerez - that Hamilton will really get a chance to get a feel for what lies in store for him in 2013.
