Medicine or Business? What should i do?

[Luis]

Hi, My name is Luis and I'm from Peru, 11:14 hs here and I'm trying to find some answers about something that i have been thinking about. In a week, 22th March to be exacly, I'm starting to study Medicine at the university. When I was in 4th grade (14-15 years old) Highschool I start to love medicine cuz I studied anatomy but when I enter to preparatory (15-16 years old) topics such biology energy etc get me mad and confused and the teacher said: "this is the moment when u have to decided what to study". I remember when i was child like 6 years old I begin to business on my school, creating the lil exchange school room after teacher class lol. My friends say that I'm good in business since that years. Actually I love to investigate about forms to get money, ideas to invest, histories of the millonaries, etc. I dont feel lethargy doing that, instead of the big encyclopedias of medicine that make me feel idk... My mother say that It like impossible to being rich instead of my father who inspirate me to continue and joking me say: "i give u 4 years to be rich lol". What I should do? My father give me the opportunity to prove one semester in medicine and if i dont like change my career to International Business Administration or Economy (i think economy is more complex). Please answer me. Im 17 now
