You have mentioned almost basic knowledge, but you have not mentioned one of the most important things, which is discretionary income. Every person should continue to invest through their discretionary income. Although you have said that investing the amount that you can keep in the long term, some people may be confused.
Emergency fund is created through our discretionary income. Creating an emergency fund from our source of income is not at all the right decision. The amount of money that remains after deducting all our expenses will be our discretionary income. From this discretionary income, we should keep money for emergency fund investments and additional expenses.
