Of course you can't find an author. Frequently these articles are created by the internet PR business, or what we call 营销号. They steal materials from various sources and stitch them together to create click-baits.
Sorry if this sounds harsh, but this piece is far from good literature. You find much better verses in Reader's Digest. But still, it took me some minutes to do the translation. Please ignore the rough edges because I only had 15 minutes for it:
Watching the seasons pass like a river. What's happened cannot be undone.
doing what you love to do
Every choice you make from now on, are made for yourself
Fewer regrets, more secret rejoice
From now on, all your tears are tears of happiness.
Yesterday has passed
However sad you are, it wouldn't help
Time don't flow backwards, day and night don't reverse themselves
Tomorrow is yet to come, whatever you expect
may or may not come true, nobody knows
What you really have is today
Some roads, if you walk on
you will be exhausted, but if you dont, you will regret
There is no right or wrong in life, only stick to your chice
Don't regret, keep on, that's it
There is a line I like: You walk on and on, then the flowers begin to bloom.
Life is like a journey on a train
You see beautiful scenes, you don't want to let go
But you have to move forward, have to leave,
Then you tell yourself: it's OK,
I'll be back someday
But in fact, the chances are you will never be back
Time passes, scenes retreat
Whoever you get to know, will eventually part their ways
Don't cling to the past
Let the loose kite fly away
Let it go, moreover, let go of yourself
Your loneliness, though defeated, is not without glory
May there be no years and months worthy of going back, and let's raise the glasses for what happened in the past.
