[sony_style]

Ok i have a big question now i want to know one thing lets said that i have 2 Credit Cards with $5000 each one so now i want to pay all my bills ( Power, Rent, Cell Phones, Car Insurance, Internet and etc. ) so lets said i have to pay in bills $2000 each month and i want to know if i can pay all the bills with credit cards each month so like that i can play around to pay all bills and credit cards bills with the same credit cards so like that i don't touch my money ? of course i don't lost track of my credit cards and my own money is only to buy me my things
Example: All bills are $2000 this month May due on May 5 so i pay with 1 Credit Card now i have $3000 in my CC and i have to pay $2000 to clear my CC in June 5 PLUS my $2000 bills again so they are $2000 de CC + $2000 the bills = $4000 due on June 5 so by this date June 5 i get my SECOND CC and i pay my bills and my CC so now im clear with my bills and my First CC this June Month and now i have to do the same thing for the next month with my First CC because now is clear i have again the $5000 back in my First CC so now i have to pay in July 5 the $2000 CC and my $2000 bills = $4000 again, so i get my First CC and pay the $4000 now for the August 5 my Second CC is clear with my $5000 back and so do the same and the same all months so like that i don't touch my own money and i will get more more credit
NOW the big question i can do that ? is good ? or whats the problem doing that i have to know ?
Note: I starter doing this in March 2007 now i have a year and one month doing that and now my credit is in the skies and i never have any problem and i have right now 6 credit cards with a big credit line, but i want to know what will be the problem in the future Thanks guys
