Step by step, 一步一步
Take it slow, 慢來慢走
You don't have to run and hide it, 你不需要飛奔而逃
Take it slow, 慢慢來
Gonna make it with a little patience, 用一些耐心就可以
Take it step by step, 一步一步
Take it slow, 慢來慢走
Take it step by step, 一步一步
Chorus:
It's like a puzzle, 就像一個拼圖
Got a million pieces, 有一百萬片
You don't have to rush and solve it, 你不需要匆忙解開它
Just take your time, 慢慢來
Gonna make it with a little patience, 用一些耐心就可以
Step by step, 一步一步
Take it slow, 慢來慢走
Gonna make it with a little patience, 用一些耐心就可以
Take it step by step, 一步一步
You're feeling stuck in your steps, 你感到步履維艱
Your heart's pounding in your chest, 你的心在胸中怦怦直跳
But you don't have to run and hide it, 但你不需要飛奔而逃
Just take your time and you'll be fine, 慢慢來你會好起來的
Verse 2:
It's not the destination, 不是目的地
It's the journey that matters, 旅程才是關鍵
So just take it slow and steady, 所以慢而穩地走下去吧
You'll get there eventually, 你將會到達目的地
With a little patience and persistence, 用一些耐心和毅力
Step by step, 一步一步
Take it slow, 慢來慢走
And we will make it, 就會成功的
Just take it step by step. 要一步步地走下去
（間奏）

Take it step by step. 一步一步
Gonna make it with a little patience. 用一些耐心就可以。
