Make full use of your "two brains"

It is better to register a needle PKM for books.

1. Changes in knowledge sources: the Internet is the largest library, but it is still less useful to me. Therefore, to collect data, you must digest it frequently to convert it into productivity.
2. It is no longer the time to remember the details: unless you are a candidate, do not remember the details; most dislike those interviews, ask what is "interface" and so on.
What is needed is the quick search capability, which can be found from the knowledge base. Do you want to remember the details again? Make full use of the computer's "second brain"
3. The knowledge base can be carried with you, and 80 GB of stuff is less than a kilo. If it's a book, it's just a car.

PKS help you manage all types of files. You need to quickly find them when using them, and directly use the integrated office functions when you want to edit and add documents.
Of course, remember what you did: When to read? How many times... these are not what a book can do.

Believe it or not, buy books quickly and read less carefully. Besides, the core value is Directory, which can be stored on the Internet .........
