Economist Ted Bauman pulled out an old laptop he had bought for his daughter. He says it’s really slow and is unable to run any of the software uses. What he would like to do is destroy it with a hammer, something that he suggests everyone does if you’re going to throw anything with your data on it in the garbage.

However, instead of getting rid of this laptop he decided to instead wipe it clean and then install a stock monitoring program. He set the laptop on the side of his desk so he can keep track of how his investments are doing, including the ones he has recommended to the readers of his Bauman Letter newsletters. Ted Bauman says that he also made double-digit financial gains in a quick and painless way and decided to show others how to do so as well.

What he did was pay off his short-term debt. Ted Bauman spent eight weeks this summer traveling in Africa and Europe. He used credit cards on this trip so that he could earn rewards. He also updated his South Africa home using the credit cards, bringing in a few hundred dollars worth of awards.

When you pay things by credit card you have a grace period before you have to start paying any interest. If he had paid interest than it would have outweighed what he made in rewards. So, he paid his credit card balances in full, saving himself a huge amount of money he would have otherwise spent on interest. In order to pay these balances, he sold some of his stocks because he would have needed to pay around 20% for interest while getting quick stock market gains in that range is all but impossible.

Ted Bauman is one of the financial gurus who works for Banyan Hill Publishing. He writes about debt, investing, housing, and the issues surrounding migration. He also writes about how to keep your personal data safe and out of the hands of the government and big businesses as much as possible.
