LONDON, England - Mercedes' 2014 Formula 1 champion Lewis Hamilton says he will go into the 2015 season mentally stronger than ever after learning to keep his personal and professional life apart.
Hamilton won 11 of the 19 races in 2014 on his way to his second title but he and on/off girlfriend Nicole Scherzinger have separated since she watched him win the Abu Dhabi season-ender - and thereby the title - in November 2014.
"I think in 2014, I adapted... a mental attitude that was kind of, I would like to say, impenetrable," the now 30-year-old told reporters in England before heading to Australia for the March 15 season-opener."
