Your lack of credit history is part of the reason. Applying for several cards at once is also a reason to deny you. If you know someone with good credit who trusts you, you can get them to open an account jointly with you.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
