Code is like a performance by musicians. They play together typically based on a plan known as "score". But when they play a piece for the first time the performance is typically much lacking. They have to rehearse the symphony or rock-opera or whatever. Removing technical debt is like playing the song again, this time better. You learn what works what not and can do it better. The challenge is how to know the code-performance is good enough.
