<prompt> Human: Hey guys quick question:I am 18 and in college and I also work around 30-35 hours a week so I make good money for my age I guess. I currently have a credit card that I have had since last year. I pay it off in full each billing period and I only use between 20-23 of my 1000 credit limit. What I have found is that I will be at a 200 balance well before my bill is due. I was wondering if opening another credit card would be a good option for me. I have no problem paying for my other expenses with my debit card after my credit card is full, I just like the idea of more rewards. Thank you!  <response>: You can request a credit limit increase if thats your main concern.Many people have multiple card strategies to maximize rewards, so as long as you can pay it off at the end of the month, its fine to get another one.Be careful of sign-up bonuses though, they often require minimum spending over the course of 3 months. If you cannot hit these limits, do not try.
