Earning money is just winning half the battle. Knowing how to keep it and use it is just as important as earning it.
Many people have reached the "success" of acquiring big fortunes but failed in maintaining it. You must know that your personal finance is almost no different from corporate finance.
Earning money is different mastery than financial planning. If you don't know how to use your earnings and create wise habits of saving, investing and lifestyle, all the money in the world won't make for truly rich life.
Remember, being rich is not measured how big your bank account is. Rather it can be measured by how fulfilling your life is.
