Hey all,
I started my journed as soon as I turned 18, because I knew how important credit would be to me as I got older. That was about 8 months ago. I had zero history to start with and neither of my parents had good credit, so authorized signer was not an option. I started with a Bank of America Secured Card with a $300 limit, used it sparingly and paid off in full for a few months. Then I made a big leap: I applied for an unsecured Capital One Quicksilver card. Surprise surprise, I got a "notice in writing within 21 days" decision. So I gave them a call, and to my surprise I was approved for a $500 CL over the phone after answering a few simple questions. This put me in Capital One's "Credit Steps" program, which meant in 5 months I would get an automatic CLU to $750. Well, I had forgotten about that and the CLI just happened. A (comparatively) whopping $3,500 CL! The interest rate is the same (20~%) so I wont be able to carry a balance, but it's nice to have none the less. My fico scores are now 690, 691, and 690 and seem to climb dramatically every month.
Tldr; There you have it, a little more than 8 months, and I went from no credit history to a 3,500 CL. Wouldn't have been possible without all the advice on this forum 
. It was easy, frankly, it just takes parience and dilligence!
Thanks for all the help, onward to greater credit!
That's awesome!
