以下是《Believe In Mi》的歌詞：
回望這一生
風風雨雨
錯過幸運
還未至命途完
心中有信念
就算跌傷仍未損
自我塑造
衝破黑暗
曾被睏倦淹沒
跌得深不見底
從未放棄
拋開過去那痛悲
跨出一步走一步
將心中的恐懼化做腳步
拋開一切不快走一步
心中有路便走一步
Come on come on believe in yourself
Come on come on believe in your heart
Come on come on believe in yourself
跌痛亦未損信心未曾變
Come on come on believe in yourself
Come on come on believe in your dreams
從今天開始新起點
今天的我決不灰心喪志
一息尚存再度跨出一步
跌得深不見底
從未放棄
拋開過去那痛悲
跨出一步走一步
將心中的恐懼化做腳步
拋開一切不快走一步
心中有路便走一步
Come on come on believe in yourself
Come on come on believe in your heart
Come on come on believe in yourself
Believe in yourself Believe in yourself...
Come on come on believe in yourself...
Believe in yourself Believe in yourself...
相信自己 相信自己...
相信自己 相信夢想...
相信自己 勇敢去闖...
相信自己 邁步向未來...
