Don't forget the road you have traveled, and don't live up to your youthful heart. Literally, don't forget the way you came and don't live up to your wishes when you were young.

The extension is, don't forget all the experiences along the way, don't forget your ambitions and ambitions when you were young, and don't lose yourself.

This is an affirmation of the past, and it is also an expectation and requirement for future life or some experiences. I hope they can continue to adhere to the good direction of the past, such as diligence, persistence, persistence in their own ideals and efforts to realize their dreams. These are all worthy of persistence. It can also be said that it is another way of saying that you don't take the initial heart.
