The second reason why you can never become rich is not knowing how to use money. There are several ways money can be use : spending, savings, and investing. Many of us already know about spending and even when we spend we spend on things that are not really needed but just to impress people who don't care about you.
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.
Let them know that they also need to struggle, if you are asked for a 100 you can give them 30 and tell them that they don't need to pay you back, that's all you can afford, think trick makes some stay away from me because they feel it's wrong asking me for help.
Not helping won't get you rich either, this is my main point to you, and the hand that giveth always find open doors easier in their struggle, it's in the Bible if you are religious, help some and don't help some.
