《I Believe I Can Do My Best》的歌詞如下：
I believe I can do my best
I believe I can make it
No one can stop me from going on
Life is a journey
Full of tears and joys
And challenges that you must face
Life may be hard
But don't give up now
Believe in yourself
And your dreams will come true
You have what it takes
To make it through the toughest times
Believe in yourself
And you'll find your way
Life is beautiful
But it's also tough
So keep on going
And never give up
I believe I can do my best
Believe in yourself
And your dreams will come true
No matter what the obstacles are
You can do it, you can do it
Because you are stronger than you think
You are smarter than you believe
And you can do it if you try
So keep on going, keep on moving
You will get there in the end
I believe I can do my best
Because I believe in me.
這是一首鼓勵人們相信自己、相信自己的能力，不斷努力向前，不畏困難、挑戰的歌。
