This is the way to go. Plus, it'll teach you how to use them. It will be frustrated maxing out all the time, but you get used to it. Bring along some cash, just in case. And use that card ALL the time. Then, when you can, get a card that gives you good rewards. Amex Blue is what I recommend- cash. Get two cards, one Amex and one Visa/ MC. Don't get any more. And then life will be easy and simply.

Oh, and pay off your credit card every month. NEVER carry a balance.
