Great questions first of all!! Business is a really wide field and stretches from management, to supply chain, change management, marketing, to business administration. What I am trying to point out is that business is so varied and that the best way to learn what you like and what you do best is to take a broad approach to business. I recommend seeking out jobs and other experiences that let you explore and become exposed to all the different sides of business which thus enables you so truly understand the whole gambit of the business world and what you prefer.
Consulting is a great path to pursue because of its ability to enable varied experiences. I am a consultant currently and I can tell you that no two projects are the same; they require different skills and different solutions. Because of this I am afforded a varied multifaceted work experience in a relatively short amount of time given that an project is usually from 6 months to one year.
Consulting is not the end all be all by any means, but it is a good place to start. If not consulting, then pursue other jobs that allow for a varied work experience.
I wish you the best and please let me know should you have other questions!!
