<prompt> Human: Just moved out from my parents house for the first time. Realizing Im missing my piano at home a lot more than I thought. Ive been playing piano all my life, and Im now looking to purchase a keyboard for myself to have in my room. I have 500 on my credit card with a limit of 1100 which Im consistently using and paying off as I go. Ive already payed off my minimum payment for next month, and I have a job with good pay to keep paying it off as I go. Im looking to buy a keyboard at about 100, which Id likely put on my credit card now and then pay off with my next paycheck, which is next Friday. Is this a bad idea? I have all my other important finances covered rent, utilities, all for this month, savings, extra money on debit for food and others. I know I can pay it off, and worst case scenario if I do end up fucking myself over, my parents are fairly well off have offered help if it comes to that. although Id rather not get to that point. Thoughts??  <response>: If you are not paying your credit card off in full each month, then you cant affourd any luxuries.Once you pay off that 500 on your credit card, you can start saving up to pay cash. If you have the cash, you can do whatever you like.
