I know nothing except the fact of my ignorance.
除了自己的无知，我一无所知。
Believe it or not, true wisdom exists in knowing that we really know nothing, we only have educated guesses.
It is humble and honest to admit that we as merely mortal human beings do not have all the answers, and in a lifetime, we never will.
There is an infinite amount of things to learn and observe, but we have only a very limited amount of time to do it.
A mortal lifetime is not long enough to know all the answers of the universe.
But we shouldn't be pessimistic, admitting the fact that we only know little about the world is a sign of wisdom, because it would teach us that we must be able to observe and research without rushing to some ambiguous conclusions, sometimes, it would be better to let things be what they are, rather than what we believe or want them to be.
In fact, it not only takes humbleness to live in a world we don't fully comprehand, it also takes courage to face the unknown as such.
As a greenhand in C and C++ programming, I really found what I know about these two languages are very little, so I try to read some classical books about them.
But it is curious that the more I read, the more confused I am.
You have every right to be a beautiful life.
你值得拥有属于你的美丽人生。
From Selena Gomez.
Cause the life is a lesson, we learn it when we are through.
What is a good and beautiful life?
What is the meaning of a good and beautiful life?
The answer varies from person to person.
Note that some successful experience from others may be not applicable in our own case, so don't be merely a copy cat.
Try to be what we really are, that is the first step toward becoming better than we are now.
