I was once working for one of the world’s most reputed financial institutions selling their most profitable product—a personal loan package or credit card.

It was on the economic recession period and I failed to meet the objective of the career—and attractive income plus performance bonus.

Although I always wish to get one of the products I sold, my salary is never eligible to be given with a credit.

I forgot about it for quite a long time since I left the company.

A chance has run across me when I bought my first car. There’re some times, if not so often, that the money is running short and I looked around and there’s no one I can request help with.

Not only the card come in handy when I’m in trouble, several times I brought the inventories through a credit card when I expected that my future income will rise fast enough to cover the interest, or I take advantage over the interest-free period.

This allows me to keep my bank account undisturbed.

However, there’re the disadvantages of credit cards if you used them to satisfied your lifestyle regardless of the fact on income.

I have some friends who use credit cards to pay off one another’s bills. This is a good example of bad control of spending.

If you use wisely, credit card can become an assets that generates interest. For me, I mostly use my card in refueling my car. It’s the most convenience payment method I can afford, and it allows me to redeem my rewards if I paid off the bill on time.
