<prompt> Human: My credit score has sort of plateaued and im not really sure how to get it any higher. At this point should I just let it naturally do its thing? Credit karma shows my account length as red or low but that just naturally takes time. Is me opening more accounts worth it in the long run as well? O I also make about 50k. Do the credit companies know that? Is that a factor?If you have any other tips i would appreciate them.Summary of my credit karma:  <response>: You are to the point of diminishing returns. Honestly, I wouldnt worry about it. It would only be for bragging rights at this point.
