2. Investing what you can afford to lose: this means that you're using your money to buy something that you can lose at any time. If that's the case, it means it will be unwise for someone who's earning 200k per month to keep investing 40k for multiple years.
Don't take it wrong, no one will be investing and still expect his investment to run on a lose, but we do encouraged that in making business, we have to understand that each has its own challenges, which is expected of us to know and be able to analyze both the good and bad side of it, while the investment we are going to make must be base on what we can afford to loose, not because we expect loss to come, but in other to help us get prepared for it in case of anytime it shows, we are all doing business in other to make profits, but not everyone understands the reason why they need to make the investment as according to how they can afford, you may discover some lending to make an investment they are not sure about, while some are diverting their asset into other investments that are liabilities and they end up loosing.
