Please don’t say because you want to become an investment banker and make millions. The job market is already oversaturated with jobless commerce/degree holders (go look on redflagdeals forums).
The only reason I went into business because I suck in science, therefore I couldn’t go into engineering. Most students will tell you they are interested or passionate etc (complete BS for high school students with no actual business experience). Going into my 3rd year I had coop/internship experience working for two top firms and found the work doable, not necessarily interesting.
