What are the two antonyms in the ancient poem "Song of Bi Ming Ri"?

I think there are three pairs of antonyms in this poem, namely:

1, come and go

2. East and West

3. Morning and evening

The original text is:

Tomorrow after tomorrow, there are so many tomorrows.

Waiting for tomorrow, everything will be wasted.

The world is tired of tomorrow, and tomorrow will be infinitely experienced.

The faint water flows east and has fallen west since ancient times.

What will tomorrow be like in a hundred years? Please listen to my song tomorrow.

Translation:

Always waiting for tomorrow, how many tomorrows are there?

I've been waiting for tomorrow all my life, and I haven't made any progress.

The world is as tired of tomorrow as I am, and it will grow old after a year.

Only by living in the present can we realize the real life of watching the river flow in the morning and the sunset in the evening.

How many tomorrows can there be in a hundred years? Please listen to my song tomorrow.

General comments:

This poem mentions "tomorrow" seven times and repeatedly warns people to cherish time.

Don't put off till tomorrow what you can do today, and don't waste time. Poetry has simple meaning, clear language, easy-to-understand reasoning and great educational significance.

The enlightenment of this song of tomorrow is that many things in the world can be fought for and saved as much as possible, and only time is hard to retain. There is only one life, and time never looks back. Don't put off till tomorrow what you can do today and the day after tomorrow. Say, "What can be done today can be done today."
