Michael Schumacher has reiterated that he has no regrets about opting to come out of retirement, even though F1 2010 clearly didn't meet his expectations.
The 41-year-old had a pretty disappointing time during 2010, and his best results were a trio of fourth places. In contrast Nico Rosberg
managed three podiums in the sister Mercedes GP car and he also scored nearly twice as many points.
Despite that though, the seven-time F1 world champion isn't down beat and added that the woes of 2010 will just motivate him even more.
"The year has been a big challenge, and in this respect my expectations have been fulfilled. In terms of results, we clearly did not meet our expectations. But then, you have to fight for the things you want to achieve, which has always been my credo," he told his personal website.
"Mercedes, the whole team, me - we are working together to build something great. Not being an easy process makes the challenge more exciting. None of us is the type of guy to just give up when faced with setbacks.
"It is the opposite, this makes us even more determined. I think I have proved over many years that I love challenges and that I am able to handle them. I have not regretted my decision to come back at all."
As for the criticism, Schumacher conceded some of it was justified and that he hasn't exactly looked good 'all of the time'.
"I can live with criticism very well, you just have to differentiate it and it can bring you forward as well," he continued.
"What is much more important is that I deeply enjoy building what we are building here at this team and that is always the best base for success because you do not need to question the motivation. And please don't get me wrong here; you don't question the seriousness either. I can't wait already to get the new season started," he concluded.
