《人間迷走》中文版：
翻開字典逐個字細看
是哪些緣由將你我送走
大夢初醒的我 慢慢行走
迷失在每一個交叉路口
嘗試改變所有一成不變
沿途景色變美我試著勇敢
生活 有時候簡單有時候覆雜得可怕
當你在奔跑時 別忘了欣賞沿途的風景
你曾經是我最美好的遺憾
也曾經是我最熟悉的孤單
人生如戲我該如何扮演
才能告別那悲傷的模樣
有時候簡單有時候覆雜得可怕
當你在奔跑時 別忘了欣賞沿途的風景
你走的路痛著你的夢想 躲在深夜痛哭以後也就那么一回事 長大成熟並不可怕 無能為力時的妥協無可奈何時也會懂一點後來成長 一些努力跟時間積累無形的獎勵就活成你所喜歡的那個樣子 別說你恨透了歲月把你還給天空活成你自己你看著眼前起起落落都是幸福勇敢做你自己不是瘋子才是瀟灑 別因為旁人而失落 做最真的自己會一直一直在身旁 不在身旁也不會被難過打擾. 就按照自己想法來的人,不會被折磨了只會被人笑話。我珍惜，而你也一定會過上你想過的生活. 別說你恨透了歲月 把你還給天空 做自己就好了! 《人間迷走》英文版：
Running through the crossroads of life,
Trying to find my way,
The choices I make,
Will shape my destiny,
The road ahead,
So full of uncertainties,
But I'll keep moving forward,
With no regrets.
Trying to change for the better,
Every step I take,
Feels like I'm leaping forward,
Life can be so complicated,
But when you're lost in confusion,
Take a look at the beauty around you,
And seize the day,
Life is like a wonderful dream,
And I'm dreaming it with you.
You used to be my biggest regret,
Now I see you as the best regret,
Because without you in my life,
I would not be the person I am today.
Life can be simple or complicated,
It's up to how we choose to see it,
When you're lost in the maze of life,
Remember to seize the day and laugh it off.
