This sentence comes from "I'm Busy, Time Machine" by the author "Mo Jun"

The original text is as follows:

It was a good time when there were few years. Don't wait for the storm. Cherry blossoms fall into the ocean.

We have gone through one exam after another, but we don't know where the future lies. We have one certificate after another, but we always feel that the road ahead is dark and we can't see clearly. We read, we run, we travel, we are with friends, but we always feel lonely. Sometimes, I am familiar with it; Sometimes, I am a stranger. How long has it been since we talked to ourselves? What the hell do I want? What kind of life do I want? And me, where am I going?

It turns out that it has been a long time, dear myself. Youth should be very busy. Let's be glad that you have come, even though we are old. Don't be too busy in youth, but remember to talk to yourself no matter how busy you are.
