Kanye West's outlook on life was transformed by a trip to the dentist.
The 37-year-old rapper - who has 22-month-old daughter North with wife Kim Kardashian West - has revealed how being given nitrous oxide gas during a visit to get treatment on his teeth helped to clarify his perspective on life.
The 'All Day' hitmaker recalled: "One time I was at the dentist's office and I was given nitrous gas and I was vibing out.
"I guess that's my version of [Apple founder] Steve Jobs and his LSD trip - when I had this first thought: What is the meaning of life? And then I thought, to give. What's the key to happiness? Happiness. What do you want in life? When you give someone something, should they give you something in return? No.
"We don't have to expect to be compensated by the person we give to. Just give."
Kanye said the gas led him to understand that being remembered as a public figure "doesn't even matter".
He told Paper magazine: "I'm a Christian so I'll speak in Christian terms: God will give you tenfold.
"Then I said in my mind, 'I'm still under the gas and getting my teeth cleaned' - but I just want to be remembered. And I immediately corrected myself. I said, 'It doesn't even matter if I'm remembered.'"
Kanye admitted his trip to the dentist was a life-changing experience.
He explained: "I came out of the gas and had a completely new attitude on everything."
