So what's my existence on earth really up to?

Someday I will be a Professional doctor, my greatest ambition in life when I was still a kid, The reason was because my aunt, sister and some of my cousins graduated from the course of nursing. That encourage me to take other kinds of profession like to be a doctor. But suddenly, all things changed when I entered grade two in this private school somewhere a little bit far from our house I won't mention the name because it is private so it needs privacy also, but this school is really good my siblings are alumni in this school. I started to think to be a soldier in the Armed Forces of the Philippines or AFP, to be a Pastor because they also save lives like doctor thats my mind setting when I was still a kid. Time pass by I grew up my height also grew I met new friends and new ideas because of my brother, he reads a lot of books, and because of that I started to think to have own small business and later on I became active in church, my father encouraged me on becoming a soldier so whats next. I decided to become an oceanographer only one school in the Philippines has that kind of course so my decision for now is to be a chef!!! what do you think???
