<prompt> Human: Hi Reddit,I am 26 years old living in NYC making 37,700 a year 935 take home every two weeks. My job provides me with health insuranceprescriptions, and I am enrolled into their retirement plan. I graduated college with a Bachelors of Science 3.5 years ago, and ever since I left school I have been credit card happy.Heres the basic gist of my situation:I live at home with my parents. I have no student loans since I got a full scholarship to college. I use my parents car when I need to go somewhere, but usually end up taking the trainbus to go somewhere. I pay 85 a month for my cell phone, 95 a month for Metro Card, and usually spend around 140 a month in food. Once a week Ill go out for drinks with my friends and thats about 45. Then some other odds and ends, like toiletries, stuff for the dog, clothes, ect, but nothing major. Every check I get I take 300 out, put it into my bank account and at the end of the month send my credit card company 600. I have 3,502 balance on it with a 13 interest rate. I have only 1250 saved in the bank which I dont touch and hardly ever contribute to. I want to stop using the card for things on Amazon or stupid stuff, but I guess I dont have any self-control. If I cancel my card will that hurt my credit score? Would asking for a credit decrease hurt my score as well? Any other tips for saving would be appreciated.  <response>: I want to stop using the card for things on Amazon or stupid stuffThen stop.Delete your saved CC info from all of the websites you buy from.If youve memorized your number, call and say your card was stolen so you can get a new number, then freeze the card in a block of ice so you cant see the number.
