Adele was told by her teachers she would never be a success
The 22-year-old singer - whose first two albums debuted at number one in the UK - constantly had to deal with the "negative attitudes" of those who told her she would be unlikely to achieve her dreams of stardom.
She explained: "I had to bear the brunt of negative attitudes from authority figures, such as teachers, who led me to believe that success was unrealistic.
"So I chose to survive rather than live in a fantasy world."
The `Rolling in the Deep` hitmaker also admitted while she was never very academic at school, she didn`t believe she could have a successful career in the music industry.
Adele added: "I`m not, and never have been, very academic - it was always music for me. I remember when I was 10, I nicked my mum`s Lauryn Hill album and listened to it every day after school in my bedroom, sitting on my little sofa bed and hoping to God that one day I`d be a singer.
"But it was never something I purposely pursued. Me and my friends at the time all had dreams and none of theirs were coming true, so I thought, `Why the hell will mine?` "
