20k card limit, and Really proud of myself!

I'm a middle aged person who had a rough first half of his life. I had 0 credit, not good or bad until about 4.5 years ago. I had to start with secured cards and very high interest on a car. But as of yesterday I refinanced my car with great rate and got a 20k limit credit card througha credit union! So for those who don't think it's possible, start somewhere, believe in yourself.
