ALL ARE JUST A DREAM

I remembered back in a couple of years ago, I had read and impressed by a short sentence.

"What if, you waking up from a long nap and find yourself in the primary school classroom, you realized that you are just a kid aged 7, and everything happened is just a dream which no high school, no university, no office, no job, no growths, no boyfriend girlfriend, no marriage, no anything that you thought you experienced it or gained it or lost it in the past few decades. All are just a dream but you remembered everything of that."

And you will know how important is your study in future, you can also know what better course to take in University;
And you will know how important to be obedient to your parents;
And you will know how important to take good care of your health, and so your family's;
And you will know how to make friends, which no false;
And you will know how to survive in this society;
And you will know how to choose your right partner;
And you will know how important to earn more and live well.

Indeed you can know how to make everything better and nearly without fails owing to everything is restarted.
Yes that is fantastic but, and so now you knew: you only live once, no repeat.
Cherish what you still have.
