Trouble breaking into the Industry?

In short, I am a sophomore from IU Kelley who is having trouble getting into a high finance career with an Economics degree since most employers look for applicants with a finance or accounting degree. I have taken time to learn about investment banking including buying a prep course so I have basic technical knowledge of finance enough to be on par or further ahead of students with a finance major but have no experience to prove it on my resume. At this point, all I have to prove is my interest and ambition to break into investment banking which doesn't count for much when trying to apply for internships since I would likely not even get past the screening process. I am lost as to where to go next: whether I should be realistic and start searching for a different path in finance or continue networking my ass off and hope for the best? The timeline of the whole process of getting into IB is also coming up so any advice from you guys would be great.
