The n power of A=( 1+X) is the formula for calculating the compound interest of investment. For example; Buffett's average annual return on investment in the past 50 years is 24.7%. If he had invested $654.38 million+50 years ago, how much would this $654.38 million+become now? A =10 * (1+0.247) 50 = $6.2 billion. Buffett's current wealth is about $43 billion, from which it can be inferred that he invested $700,000 50 years ago. I wrote the story of "Frog and Water Lily" in my previous article, which reflected a typical crisis from quantitative change to qualitative change. And its curve is very typical a = (1+x) n.

Since the popularity of mobile phones and the Internet, the mode of information dissemination has changed from official exclusive release to private forwarding. I have received several short messages related to food safety, such as; Bananas, beer formaldehyde and Hainan's "Happy Life of China People in One Day". Mobile phones and the internet have multiplied the speed of information dissemination, which has really become a good thing and a bad thing has spread thousands of miles.

Americans once did an experiment, in which a person can know the president through a few people at most. Suppose everyone has 50 very close friends, it takes about 5 people to know the president. The formula is a = 50 5. This experiment can explain why in a strange city, everyone can find someone they know or through friends.

The quantitative change to qualitative change is a = (1+x) n, and so is investment. Many people value X very much when investing, while real investors value N more. Buffett's greatness lies in that he understood this truth at the age of 20, so he can now donate 37 billion. Nowadays, many people who have just started investing or financing always feel that they are one step behind others and have not caught up with Big X in the past year. However, from the perspective of investment, you can invest at any time. From 100 to 100, there will always be an environment like Buffett. Just study how to make your n bigger and bigger.

Note: n represents the year in the investment formula. Number of representatives in information dissemination.
