going back to school

im contemplating going back to school... and literally full time schooling. It never crossed my mind until i came across some ad for Diploma in Vet Technology offered at TP. And seriously, no one took me seriously, my mum and Rave included until i said i am Going to the OPEN HOuse. so ..... to cut the long story short, i am seriously considering taking up the course. but of coz .... there are only 30 places available so how lucky do you think i will be. its like trying to kanna 4d leh. haiz, but i am still contemplating.
pros : i always wanted to be a vet ( at least i am half of it if i do take the course)
i will get to work with pets the rest of my life
i will be able to kill all cats in the world
i can save money by not making unnecessary/ expensive visits to the vet

cons : i cannot work for the next three years.
i will not be able to play maj as much
i must be careful about not getting pregnant
i cannot go for holidays anytime i feel like it

so gals...... i will just apply and then see how...... if i do kanna 4d, then we will rethink the situation.
