Why did you choose my career?

Well, when i was a child my dream of my life was to be a doctor, able to heal everybody of any illness, but dreams are dreams and not always can come true. when i finish the high-school i realice that i not have the intelligence to be what i want to be, so i decided to explore other options. i like very much the science, specifically chemestry and biology so i decided to study biochemestry at first option, but, to be honest, after see the future of the biochemestryst in work, i don't like the career because the workplace is to poor. The most of the biochymestrist Works in investigation because they have no quotas in another Works like the SML(servicio medico legal) etc, thats why i don't like de career and i have to think to change the carrer to chemestry and farmaceutical industry, because of 2 reasons:
1)It has a good salary
2)You don't need a tesis at all to have the diploma, you can do a ''prectice'' in some industry and they evalue you and you will have your diploma too

I have another options to biochemestry, but i can't take them because i have a low score in the test called PSU. that options were medical technology and nursery.
After the time that i past in the university it was a good experience, i meet good friends and teachers, and without them i will not be what i am now.
Well, i hope my future job were the one that you work in a defined Schedule, a good salary and great coworkers.
