The 31-year-old English musician always tried to stay away from the "celebrity" side of being a successful singer, reported Digital Spy.
"(I haven't felt good about my music) for about the last ten years. I felt embarrassed to be me. It's taken me this long to feel confident about myself and to accept that not everyone's going to like my music and that's ok. I used to take things really personally when I was 21.
After three platinum-selling albums, the burden of topping the charts does not bother the "Broken Strings" hitmaker any more.
"I'm more confident in what I'm doing now and I'm not worrying about the success. The success for me is how you feel about your music rather than chart sales. Back then if I didn't get a chart position I felt bad and like I was shit. I don't feel like that anymore," he said.
