Hamilton is currently 52 points behind championship leader Sebastian Vettel.
“I come here, it’s the same old every year,” he said.
“One race win and people get excited, one bad race and negative things [are written].
“I’m just there to do my job and continue what I’ve been doing. I come here today feeling more motivated than ever. It’s great knowing we have a car we can compete with. Ferrari and others will make a similar step but it’s great we can come here and fight with those guys. There’s a long way to go but generally my second half of the season has been stronger [in the past] so hopefully that’s the case this year.”
Hamilton also admitted that he did not expect to win races in 2013.
“Definitely not, last year I analysed everything and made notes: how important it was to see whether they [Mercedes] knew where they were. When I was made aware of their plans, it was part of what helped me make the right decision.”
“I had confidence but I thought we’d start the season further back, I didn’t anticipate wins.”
