I should also note that I've had multiple friends who gave me this exact advice, then ended up with thousands of dollars of credit card debt a few years later because they got carried away. No thanks. The reason these offers are made available is because cc companies know this will happen to a lot of people.
I wonder if there’s an opportunity here for a “free travel consultant” who will sign up for credit cards for you, take a cut, keep you up to date on the benefits you’ve accrued, and act as a travel agent, booking trips in a way that maximizes the value of the benefits. If done well, it might make life simpler instead of more complicated.
That really isn't necessary. I haven't paid a single cent in interest in 18 years. Get the credit card, buy a few things, pay it off and throw the card away.
If you have a business you most likely have the discipline to not be stupid.
