<prompt> Human: Ive been doing this for about 10 years now and it seems to be easier to keep track of where exactly my money goes. I use a Chase Sapphire Preferred card which has great rewards like cash back, discounted trips and other. Are there any downsides to doing this other then the fact that you can NOT forget to pay it at the end of the month.  <response>: No downsides, this is what I and a lot of other people do. A minor point is you want to keep your utilization percentage low if youre planning to apply for credit soon, but otherwise it is a no-brainer.
