I have learned advice from books about being successful. And there it is stated that the people we call rich have at least 3 sources of income. And to achieve financial freedom we need at least 7 incomes. Such as salaries, dividends, rental properties, capital gains and many other types.
I agree that we cannot rely on saving in the bank or FIAT because every year the value will be lost due to inflation. Investing is better than saving. And don't forget to keep preparing emergency funds if something unexpected happens.
That's as reference material that you can use when you intend to do direct practice because reading books might provide insight for us to put into practice. My question is how far is the impact after you have read many books that tell how to get out of financial difficulties? I think to achieve financial freedom you don't need to have all of these seven points because talking about financial freedom is different from the stage of achieving wealth. Savings are also needed as an anticipatory measure if something unexpected happens because if needed you don't need to sell your assets.
It's just that you can adjust the percentage of savings according to your desire to achieve a level of financial freedom or in other words to grow a much more developed investment. Savings are not productive because the longer the money we save will lose value and sometimes we only need to save a few percentages as a preparatory step and it is impossible to talk about investment or anything if someone does not have savings as a necessary step.
