Hollywood star Matt Damon, who won an Academy Award for the ‘Good Will Hunting’ screenplay he co-wrote with Ben Affleck, has said that he has to work with a partner on his writing projects because he “can’t do it” alone. The ‘Bourne Identity’ star recently teamed with ‘The Office’s’ John Krasinski to pen 2012 drama Promised Land. Damon told Radar Online that he needs to team up with a writing partner on all his projects as he struggles to concentrate when left to work on his own, Contactmusic reported. The 42-year-old actor said that he was an English major at college and he hated the solitude of just staring at the computer screen as it drove him nuts.
