She admitted to The Sunday Times newspaper that music has served as a vital part of her life, even when she was younger. The 24-year old performer said that her schoolmates used to bully her because she was so passionate about music and, she was determined to make it in the music industry.

Swift share that music "filled in the gaps when I didn't have acceptance at school, when I didn't have friends, because they just couldn't relate to how much I loved music."

She said she was never boastful about her love and talent for music, but her schoolmates were probably annoyed by the fact that she believed in herself.
