The 'Candy' hitmaker said he had grown tired of his career after the moderate success of 'Reality Killed the Video Star', 'Rudebox' and 'Intensive Care', reported Contactmusic.
"I feel like my navigation system was broken back then and like I wandered around aimlessly. It was liberating anyway. However, I didn't really care about my career in 2006. I just felt incredibly lethargic and like I couldn't live up to the requirements of being a pop star," he said.
Asked if he wanted to quit, he said, "Quite definitely. Mentally I had already waved my career good bye."
Williams, 38, had already decided that he wanted to give up music for a career as a painter, but found his skills in that discipline were quite limited.
"I had started to paint and wanted to become a serious artist. Unfortunately I'm an awful painter. And I'm not very good at making radical decisions. Otherwise I would have called it a day."
