Entrepreneurship involves starting to invest in the stocks of my own company. However, unlike open-market stock investments, here you invest in your own business, not someone else’s. My company’s performance directly affects my shares. To excel at investing in your own company’s stock, focusing on one key area can significantly boost your chances of success. Conversely, to be good at investing in others’ stocks, it’s better to understand multiple business sectors rather than just one. Since investing in stocks focuses more on minimizing risk than maximizing returns, diversifying resources across several areas makes risk management more effortless. If you master risk aversion, you can reduce losses and increase your chances of surviving in a volatile market. If you are knowledgeable and well-informed, I recommend investing in others’ stocks rather than pursuing entrepreneurship. - Joseph’s “just my thoughts”
For the security of the Internet service, we have been asked by the Internet service companies to set the password combined by more than 8 or 10 "uppercase letter+lowercase letter+number+special character". But it was obviously of no use. This security guideline was recommended by Bill Burr who worked at NIST in the USA, he suggested this way in his report. Furthermore, the user was required to change the initial password set regularly. Despite this measure, the best way of security to protect users' accounts was the notification of the alarm for attempted hacking when the hacker tried. We have only tried to change the keys despite the simple method meanwhile. Today, the world has begun to comprehend that the security problem is not encryption or confidentiality, but simply cyber-dominion control and communication. - Joseph's "just my thoughts"
