London: "Harry Potter" star Daniel Radcliffe says he struggles when he doesn't work because he feels guilty and agitated.

The 22-year-old actor, who shot to fame at the age of 11 taking on the title role in the "Harry Potter" franchise, said he has no desire to take a break from acting as he finds it really hard to be away from a film set, as reported.

"I find it really hard to do nothing. I've been conditioned to work. I've worked since I was 10 every day, so when I'm not working I get bored and agitated and feel guilty, like I should be doing something. Honestly the happiest I ever am on a film set. It's my favourite place in the world, so it's not a hardship. I'd rather be working than on holiday," Radcliffe said.

After the "Harry Potter" films finished last year, Radcliffe admits he did think about a career change but decided he loved acting too much.

"I've thought about it but actually I love my job. I want to act for a long time, for the rest of my career, but I'd also love to direct. I feel like I'd be good at that. I don't know why. But that's a while off," Radcliffe added.
