Forty years ago, being able to drive was a "permanent job". Thirty years ago, knowing English and being computer-savvy were rare talents. Twenty years ago, a one-cent text message from China Unicom and China Mobile during the Chinese New Year could easily earn billions of dollars. Ten years ago, owning a taxi was like sitting back and enjoying the fruits of your labor. However, times are changing rapidly. Today, taxi drivers have never expected that private cars, shared bicycles, and shared electric vehicles will blossom everywhere and snatch their market. China Unicom and China Mobile also did not foresee that WeChat would leave the SMS business with only the verification function. Traditional digital cameras did not expect to be replaced by smartphones. Even instant noodle giant Master Kong did not expect that it would be defeated not by its competitors but by the emerging food delivery industry. The most stable guarantee does not come from insurance companies, but from our own continuous progress and ability to keep up with the times. The reality is cruel and real. It is often not the competitors in front of us that eliminate us, but the rolling trend of the times and the ever-changing technological progress. Therefore, we must ask ourselves: How long can the existing skills and abilities last? Five years? Three years? Or one year?
