To let money appreciate, one must face the laws of money. 1. The world is very large, and there are always opportunities; what is lacking is money. Wealth comes from your retention of money, that is, if you want to be rich, you must first learn to save money. 2. Understand the power of compound interest and learn to invest. The three important factors that determine returns are: time, rate of return, and principal. The simplest calculation method is the Rule of 72: 72 ÷ rate of return = the number of years required to double the investment. For example, if your annual rate of return is 12%, then the time required to double 10,000 yuan is: 72 ÷ 12 = 6 (years). 3. Seek certainty in uncertainty and gradually become rich. Investing is like driving; the core of driving is to avoid accidents. As for how fast you reach your destination, you will eventually arrive at the big destination. As long as you get there, this journey is concluded perfectly! Investment is the same; the core of investment is not to lose money. As long as you don't lose money, whether the compound interest is 5% or 8%, you will gradually become rich. 4. Believe in the power of belief, because you believe, so you see.
