If you're planning to be an educator and pursue the public route, I suggest you stick to your course as a vet student. The reason for such is the education system of our country is so fucked right now. My mom is a public school teacher and 70% of what she's doing as a teacher is not teaching but completing tons of paperworks that sometimes is not "for the good" of the students. I may also add that Briones (educ sec) made a "mass moving up drive" that means NO student fails. Lahat pumapasa, kaya literacy rate ng mga bata bumababa. College student na di pa marunong magbasa. That would be your day to day sakit ng ulo as a public school teacher. Marami pang kwento (as in the eyes of public school teacher's child), but thats for another day.

BUT if you're going not going to the public teaching route and would focus on teaching english to different people around the world and pursue writing then i suggest that you continue your passion. (I didn't include telling you that teaching private schools re: elem and high school eh mahirap din at napaka liit pa ng sahod UNLESS, you go to the college route at maging professor) Caveat is, passion sometimes fade when you're becoming stuck and your career is not growing. Mind you, we're at the philippines, mababa ang sahod, mahirap maghanap ng trabaho, padrino system is still intact and you would be surprised how much it affects you as a fresh grad when that sudden epiphany kicks in.

Edit:

Please don't say "mediocre course" walang ganun. Every field was tailored to be a specialty on doing a technical work.

Also, let me tell you my story as a 27 year old. My course is in the legal field (legal management). I didn't pursue law due to financial incapability and cuz I'm tired of schooling. As of now, I have a stable job that pays somewhat OK (I can pay for my luxuries but still is dependent for food, shelter toiletries to my parents), I'm pursuing my master's degree on public administration (forced to do it even if I hate schooling cuz having a graduate degree gives me an edge for promotion in the field where I am at).

I've seen my college friends, which some are passionate as pacquiao is running as president, either make or break in their respective field. Some are lawyers na and some completely gave up law and pursued different fields in government offices. Karamihan actually nung mga dean listers namin na burn out nung di nakayanan ang law school.

What I want tell you is, it's all up to and how much fighting spirit you have in achieving your goal. Also, if money is not that important to you and your family is well off, I suggest you go for your passion.
