・In order to build wealth, what was more important than anything else was not when to buy US stocks; what held the key was to keep buying (p13) It wasn't about when and how much what kind of financial assets you should buy, but just keep buying. Officially, this approach is known as the “dollar cost averaging method” (p15)
・What to focus on depends on the economic situation at that time. If you have few investment assets, you should focus on increasing your savings, and if you already have large assets, you should spend time planning your investment. Savings are for the poor and investments are for the rich (p39)
・The advance and decline of humans has evolved to save energy as the amount of exercise increases, and in order to lose weight, it is more effective to change the content of the diet rather than increase the amount of exercise (p65)
・The reason why many people cannot get out of poverty is not because of their motivation or ability, but because they are in low-wage jobs where they can earn only a minimum income to live. I don't have money, so I can't get training or funds to get a high-paying job. This is a quagmire of poverty (p74)
・The royal road to becoming rich is, ultimately, investing in assets that increase income and generate profits. Of course, you should be careful about your expenses, but you don't have to keep putting up with time to enjoy a cup of coffee for the rest of your life (p75)
・The ultimate goal of a wealth building journey should be “becoming an owner,” that is, using the increased income to acquire assets that generate further income. Human capital must be converted to financial capital (p85)
・When doing luxury shopping, always invest the same amount of money; this is a double rule (p93) What is important is that when you try to buy something, prioritize how to use money that gives you a sense of fulfillment, which is whether or not you feel that it is luxurious (p94, 95)
・As a way to use that enhances fulfillment and happiness, 1) buy experiences, 2) do luxury for yourself, 3) buy time in advance, 5) use for others, and increase a sense of fulfillment, autonomy (being autonomous), proficiency (improving skills), and sense of purpose (leading to something larger than oneself) are convenient standards (p97) not what to buy, but what criteria to buy based on (p98)
・Having financial leeway to buy a house means making 20% of the house price as a down payment and a loan ratio of less than 43% to income (p144)
・ It was found that there are extremely few cases where principal is exhausted after 30 years if the 4% rule is implemented, but there seems to be a limit to setting a revocation rate higher than this, and historically, it was found that there are cases where this rule goes bankrupt even though it was calculated with a 5% revocation rate. In order to achieve the 4% rule, assets 25 times the expected annual expenditure in the first year after retirement are required, and once this amount is reached, they can be retired (p167)
・For retirees without labor income, the only weapon against inflation is to increase investment assets, and those close to retirement should be especially careful. If you want to minimize the effects of inflation, money other than life defense funds should be invested immediately (P191)
・Investing is creating financial assets that continue to generate money even when you stop working, and this is probably the most overlooked even though it is the most persuasive reason why you should invest (P195)
・As a reason why individual stock investments should not be made, this is because it actually generated excess returns on stocks that surpass US short-term government bonds, which is why it is better to buy index funds and ETFs and hold stocks in a wide range of stocks (p242)
・The only time that installment investments significantly exceed immediate lump-sum investments is at their peak before a major market crash (1929, 2008, etc.) occurred, and everything else is generally lower. (p261)
・There is no point in saving cash by waiting for the bottom price; the dollar cost averaging method is a far superior investment method, and the faster the investment, the better. When these are combined, the conclusion is “you should invest as soon and as often as possible” (p289)
