Buying liabilities, things that doesn't have value five years from now. Many save but even when money is saved, it is done to spend and not to invest and the only way to become rich is to invest and not by savings. So , invest in assets and not liabilities.
Would you say a car is a liability? I use the car for logistics services and I know quite well that it will depreciate in value five years from now. So, how would you classify this- a liability because it will depreciate in value in the coming years or an asset because it will increase my company's revenue in the coming years?
