on credit cards

I sometimes forget to keep in mind the due dates of my bills - cards and mobile phone. I'd end up paying for late charges because I'd lost track which bill is due on which date. I should avoid this circumstances because extra charges are the last thing i want. Maybe it's high time i should give up all my other cards and get a high limit credit card instead. By then, with just one card, I wouldn't have to think about so many due dates.
