'I try to follow my heart and dreams every day of my life and I think that's why I am where I am today.'

'It means so much to me to have a fan like you who takes the time to sit and write me such a touching letter. Your letter was both touching and sincere. I wish you nothing but the best in the future and hope you keep smiling.'
