Lewis Hamilton has vowed to be at '100 per cent' this season after admitting he wasn't focused enough on the job at hand last year.
The McLaren driver endured a difficult season both on and off track last year, with issues in his personal life away from the circuit and a number of controversial clashes on it.
Amongst those incidents were more than one collision with Ferrari's Felipe Massa and a controversial weekend in Monaco, which ended with the Briton attacking stewards for the penalties he was awarded.
However, for 2012, Hamilton insists that he approaching the new season with a clean slate and won't allow anything to get in the way of his title challenge.
"There were times last year when I was juggling too many things,” he told The Observer
. "There were too many things hanging over me, too many things which were unfinished, questions in my mind, whether it was purchases, investments, management, lawyers or family.
"There were lots of things and I didn't have the pieces of the puzzle in the right place. I was all over the place last season. I didn't think anything was a positive. But I've corrected things and now I've got a clean slate. I've got nothing worrying me.
"Last year I was battling everybody. I was having trouble with stewards, I was having trouble with many different people. I want to fix that.
“I'm looking forward to having a good relationship with Felipe and from the end of last year I've been working on my relationship with the stewards. I've got to stay out of trouble so I don't have to visit them so much.
"I wasn't operating on all cylinders. There were times when I was on good form, but still not one hundred percent and that's where I want to be this season."
