But saying that we should invest with an amount you can afford to lose makes it looks as if we are gambling or we are trading, this is an investment, no Investor will be happy losing his hard earned money, so in my own opinion, the right statement for such phrase is invest with an amount you can do away with for a very long period of time.
You are making the statement very complicated. Losing money does not mean that you are going to lose the money or that you will easily lose it. You can take this word to mean money that you will never need to meet your daily needs or meet basic needs. Or even if that money is ever lost, it will not affect your quality of life or you will not be paralyzed. I will not say that after investing with losing money, you will not regret it if it is somehow lost, this sentence is not realistic at all. A person's hard-earned money is always valuable and if its amount is very large, then you will definitely regret it if it is lost.
Choose money for investment that if it is lost one day, it will not have a negative impact on your quality of life. I find the definition of losing money as you have mentioned a bit confusing. According to your definition, if you need the invested money before achieving your goal, then what will you do or how will you mention it?
This s the most important and effective point. An investor should use such amount of money for investment that his life will not be adversely affected if the money is lost from his life. Yes we know money is very important in every person's life but still but to achieve success in life people have to take financial risks. Many times investors do that they invest all their savings at once and get excited when after investing they don't see good results in a short period of time.
Investment but not job that here I invested some amount of money and at the end of every month my profit came from it. Before investing, investors should invest with a clear understanding of the fact that after investing, his money can be lost and profit can be made. Investing does not mean that he will make money for sure. But if you have enough patience and believe in the market, investors can definitely get a good result at the end of a certain period of time.
