Maintaining even a small annual profit is advantageous in investing. Survival remains the most critical factor in business. People have sought the secret to Warren Buffett’s success, which is the power of compounding, but they overlook the real key: he has invested consistently for 75 years without pause. You can indeed succeed in your business endeavors through sheer survival; conversely, you cannot survive solely because of your success. Survival is only achievable if you have the strength to keep going, even with minimal returns. To do this, you must do what you love. Invest in stocks you like, and continue investing even if it is volatile. Next, you need to secure a “margin of safety.” Even a small margin ratio is crucial because a business can’t survive without margins. Frugal spending, flexible thinking, loose schedules—anything that helps during tough times—can all contribute to building a margin of safety. - 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"
