Every kind of knowledge is likely to develop and update, it may become obsolete with the development of the times, so we should constantly update our knowledge system.
For example, you originally in C + + convenient accumulation of some knowledge, the use of c++98 standards, but now c++11 in popularity, c++17 immediately out, you need to update.
For example, you used to advertise, take the traditional TV, radio, magazines, newspapers and other media, accumulated a lot of knowledge and experience, but now the internet era, the public number, Weibo, headline number, Ying Guest, pepper a variety of new media, you need to update the knowledge and experience of these media.
If we cannot update our knowledge base regularly, we will slowly lag behind the times, become less valuable and lose many opportunities.
For a simple example, Java friends, when Google released the Android system in 2007, how many people took the opportunity to incorporate the Android development framework into their knowledge system? If you started to do Android at that time, you caught the tide of mobile development, now is not the big God is also big coffee.
To give a simple example, drip and fast out, many taxi drivers do not believe that they will give themselves to pay their own subsidies, not willing to install the corresponding app, the results not only earn a very substantial subsidy, but also missed the opportunity to optimize the efficiency of soliciting.
In fact, when we build our own knowledge system, we also follow the rule of the width after the first depth .
