New to Consulting - Where to Start?

Hey guys,

I (20M) am a business student here in Berlin. I am quite new to the world of High Finance, as I only became interested in it after my first job as a waiter. Working as a waiter, I experienced firsthand just how brutal the reality surrounding money can be. I then decided to work on my financial literacy, as well as working on breaking into Finance. I have taken a big interest in Consulting, and I've already started the recruiting process so that I may find a job/traineeship once I graduate. I've already started cold emailing, networking, going to job fairs, coffee chats, etc. However, I would like advice on the following:

Given that I am not confident in both my current level of knowledge and my techs, what material would you suggest I look into so that I may become the best Consultant I can be? What books, courses, seminars, etc. should I look into? 

Any and all information regarding this matter is very much appreciated.

Thanks.
