is something that the Rich know that the Poor don't know. You should never have more cash then the amount necessary to take care of your reasonable needs and wants. Use the rest to produce more for everyone. Even if you can only invest $5.00 per month, it's better for you if you do.
Always budget to spend less than you make. Always try to improve yourself. Always try to invest something in some way. That is the difference between the rich and the poor.
Those that don't will become poor, even if they start out rich. Those that do will grow richer, even if they start poor.
