Debt is not inherently bad; it belongs to someone else. The goodness or badness of debt depends on the circumstances, terms, and conditions of borrowing, and it is not necessarily negative. Debt should be acquired when I have a stable income or additional profits to invest, rather than for consumption. However, you should avoid using it for highly volatile investments, such as cryptocurrencies or stocks. You need to control the debt; it is considered good when you can manage it under conditions that allow you to repay both the principal and interest. The advantage of debt is that it provides the opportunity to grow faster than others in a competitive environment. Debt belongs to someone else. This is the key. - 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"
