Taylor Swift insists that she avoids reading any positive or negative feedback about her music and people's opinions on her life because she insists it would ''lead to insanity''.
The 23-year-old star says that she tries to block out any feedback about her music or her personal life because she could be "easily" be left unbalanced.
Speaking to Glamour magazine, Swift said: ''You can be obsessed with the bad things people say and the good things, either way you're obsessed with yourself and I'm not - you can become unhinged so easily.
''Vanity can apply to both insecurity and egotism. So I distance myself, because I feel everything.
''The little I am exposed to hurts my feelings. The only things I can really control are my songs and my behaviour. The rest? If I focused on it that would lead to insanity.''
Swift also says that Miley Cyrus should be forgiven for her controversial twerking routine at the recent Video Music Awards: ''There's room for role models who make mistakes. There's clearly room for role models who are made fun of at award shows.
''Not that I necessarily enjoy being poked fun at, but that's gonna happen to the fans, too. Whether in a board meeting or in school or on Facebook, where they'll get humiliated publicly.''
