<prompt> Human: I opened my first credit card last year, the Fidelity Rewards Card. All my earned money back goes to my IRA, I love it :DWhen I opened my first card, my credit score was at like 650, and Ive been on time with all my payments, Ive behaved myself, and keep my credit usage to 20-30. Last one I was at 29 moved and had to get some new stuff.So in a year, with 1 year of credit history, Ive gotten to 726, and Im happy with the trajectory-but Im wondering how to go further. What Im reading is that I need a longer credit history just gotta wait that one out, and more lines of credit I...only have 1. My 2016 elantra was bought outright, and no student loansdebts to my name.My credit limit is also 5,000. When I got that card a year ago, I was making 66,000 a year, and now Im making 123,000 a year.Im uninterested in spending more money, but was also told my utilization of 20-30 is too high-should I request a bump? What should I bump it to? Will this help?It seems like I have nothing negative against me, which is great, I just am new, and wanting to make things better!  <response>: time! continue to be a responsible credit user forever, and your score will continue to rise forever. ITS THAT EASY. it takes years and years and years and years and years. Be responsible FOREVER.
