<prompt> Human: Hi everyone!Im 25 and Ive never used a credit card. I grew up with a financially irresponsible parent and saw the effects of bad credit and poor spending habits, and wanted to avoid the rabbit hole.However, Im traveling to Asia with some friends this summer. I have about 1,500 budgeted for my spending money there flight is already booked and my friend mentioned that she is getting a Chase Sapphire Rewards Card for the trip because if were already spending a few hundred dollars in less than a month, might as well get some cash back or travel points out of it. Im highly considering doing it for the trip, paying the balance in full with the money Ive already tucked away, and then abandoning or closing the card when Im back in the states. I didnt tell my friends because Im embarrassed but I know very little about credit cards... Is this financially responsible and possible? My credit score is almost 800 student loans woohoo so I think I would definitely be eligible. Any advice is appreciated!  <response>: Avoiding credit cards in general is short-sighted unless you know you have self-control issues you cant overcome.Avoid using them irresponsibly and they can be a great asset.
