So, I was 18. Well, since the fake age will be gone, if I redact it, I was 17 years old. Since I was born, I haven't had any luck with my choices, but I sent letters to about 30 people to make pen pals, but I didn't get a single reply. So I gave up on making a pen pal, but my sister said that she wrote because there was a pen pal advertisement in a biweekly comic magazine, so I wrote only the first one. The pen pal ad was two pages, but only the first one. I tried more than 30 times, and I asked what else to challenge, and I said no, but my younger brother told me to write a letter, saying that he had written it down and that a reply would come this time.
An indispensable aspect of financial technology is the power of compound interest. The word compound interest is a combination of the Chinese character bok (hyeon), which means overlap, and the kanji li (je), which means interest. This means that interest is charged on principal and interest. And that means that interest is charged on interest on interest.
