To invest, a person needs to find a source of stable income and from his stable income, he needs to extract discretionary income through proper financial management. Because investing with discretionary income is very good because the amount of money left after deducting all your expenses is discretionary income. If you invest with discretionary income, even if you lose, you will not be in too much financial trouble. Because you have invested with your remaining money
It is not something that only discretionary income will be from a stable income source. For example, there are many people whose work is not stable. They work on daily wages. Again, there are many people who are paid when the contractor completes their work. So we can never say that discretionary income has to be derived from a stable income. A person can derive discretionary income from any of his sources of income through proper financial management.
It is very important for all of us to have proper financial management. Because if we cannot manage our finances properly, then maybe after a while we can put our holdings at risk or may fall into risk. If our expenses are more than our income, if we cannot control it properly, then maybe after a while we can get into debt or we may have to sell our holdings due to the need for money.
