Hi, robywater, welcome to the forums! . . .As jdm said, it's all about the util, which you can control.
Additionally, since you have quite a few cards plus a few student loans (don't know what else), you might want to shoot for letting only 3 or 4 CC's show a balance at any one time, with the others paid off. You can use the others, but just pay them off to $0 when they show up online. I would especially recommend paying off store cards the moment that they post, unless they have a 0% on new purchases offer, because store cards typically have high APR's, and they can be pretty squirelly about updating to your credit reports.
This can also help maintain your sanity by not having to keep track of 11 different balances, 11 different statement dates, and 11 different due dates!
