Kelis ''dropped out'' of the pop race a ''long time ago'' and is just content to be making music and performing.
Kelis doesn't feel she needs to ''prove'' herself any more in the music industry.
The 34-year-old singer - who released her new album 'Food' this month, her first on UK indie label Ninja Tune - doesn't worry about chart success anymore and is happily ''out of the race'' when it comes to competing with other pop stars.
She explained: ''I have far-exceeded anything that I could possibly imagine in my career and I feel really blessed and really honoured to be upheld with such super, super, super, talented people.
''So that being said, I don't know if I'll ever stop, but I dropped out of the race a long time ago, know what I mean? I don't feel competitive at all. I don't feel the need to prove myself. I have proved myself far beyond - I could go on forever, you know.''
The 'Milkshake' singer - who has a four-year-old son Knight with ex-husband Nas - feels ''really grateful'' to have had such a successful career and doesn't feel like she's ''running on that rat wheel still''.
She added to SPIN magazine: ''Right now, my responsibilities are to be sane, happy, and blessed. I feel very blessed, I have a child who requires a rational, sane thinker. He deserves that, so I can't afford to care that much about things that don't actually deserve caring.''
