In this world you have to be wise enough that you have to look for a lot of sources where you can earn for your own sake. And if you are a person who likes to roam around the world, you have to be financially stable. I think the best way to know you are secured with your finances is that you have that self-discipline to control your income and expenses, you have to know your debit and credit so that you will not be deficit at the end.
that's right, if I myself I prefer to avoid credit cards and the like, because credit cards will only make our lives uneasy and make our finances messed up. away from credit cards is the most powerful solution to get a comfortable life without the thought of paying off all our debts that if using a credit card.
