WHY I CHOOSE MY MAJOR?

Well, in my childhood i wished so many jobs, like a teacher, doctor, fireman, veterinary, painter, animator, artist, profesional dancer, etcetera, because there are areas that i liked so much to my younger me, ever of the evers I've been in love with animals and take care of them, at the same time I wanted help and save people with my own hands, taught things for the future professionals, I loved and I still love all the artistics things like theatre, dance, draw, paint, etcetera. But well, the future me, even if I still love all the things that I mentioned before, she take love for the science of the life, like biology, chemistry and physics, so then, after of hours and hours, days and weekends of thinking, my options were reduced to a three principal options: Medicine, Chemistry and Pharmacy or Biotecnology. At the fist time, I've been obssesed with medicine and that's was the reason of why this mayor was mi first major to choose and my priority, but at the pass of the time, I still thinking about it, and make sence about what are really want to do with my life and the answer was: "I'll be really happier if I work to the science, in a laboratory, making science with my own hands, discovering big things" that's what i thought, and actually I confirmed, I'm really happy with the major that I choose, even if it's difficult the most of the time, even if required losts of effort, and sacrify sometimes, even if sometimes it's really tired,  I'm totally gratefull and happy that I ever been thingking.
