WHY DID I CHOOSE THIS PROGRAMME/CAREER?

When i was a child i didn't think in the future or what i will do. My father always wanted that i study Medicine, and with the pass of time i acquired this taste for this profession but when i grew up a little more i didn't consider my passion. after to finish the school i wanted to be a chemistry teacher and i don't understand why didn't study pedagogy.
When i was finishing the school i thought about being a Veterinarian, but i love animals and it's hard to me to see them suffer.
Finally, when there was a month left to take the Psu i started researching careers, and i didn't know what to do. After to the PSU, I've enrolled in the bachelor's program, but i didn't foun a career that i really loved, Two years later i found Chemistry and Pharmacy, my friend talked to me about this career. I researched about the labor field and i discovered that i could work in many areas, inclunding job realted to investigation and toxicology.
Now i'm here and i ca say that i don't regret, i'm happy whit my decision, but i have had to learn to overcome my frustation, becaude this career is not easy, but wherever, nobody said it will be. Npw i just want finish my studies, i hope to take a specialization too because i really want to work in investigation areas o in the SML.
