No one loves to lose money. Don't tell me to invest what I can afford to lose; tell me things I should do to avoid losing that money or even minimise the risks of losing that money.
If you are not losing a lot of money, you are most certainly not making a lot of money and will never be rich. This is the irony that the person with a poor mindset does not understand. Most humans on the planet have a poor person's mindset.
