Than to be here on my own

Than to cry over spilled milk
不會為了一點小事就流淚
So I'm gonna rise up and let the world know
所以我要振作起來，讓世界知道
That I'm not done with this show

'Cause I know that I can do it

I know that I was born for more

Than to settle for less than my best
不會滿足於平庸的生活
I know that I was made for more
我知道，我天生注定擁有更多
Than to sit around and stew in my stress
不會坐視壓力積壓在心頭
So I'm gonna rise up and let the world know
