My future.....

Nowadays,i'm starting to have a strong interest in cars,especially supercars(high performance cars)......
I can pinpoint any type of car, what model, what brand, how much is the power... and so on.......
Others just say, its so typical.... boys......... likes cars and girls.....haha.....
But,i also have big interest in research and development on eco-friendly cars too.....
my mom says that automotive is just mechanics.... all those filthy jobs......fixing engines,changing oils.....
but i dont think so......
For example,Honda: hybrid cars are selling like hot cakes....... and those technicians are all working in air conditioned labs.......the pay is quite good also.......
another example: Merc, have you ever seen mechanics in their 5S showroom looking dirty,NO!!! they all use electronic equipment..... no need 2 dirty ur hands again....

im quite lost now..... i dont hav the confidence in setting up a carreer in automotives..... but i cant waste my talent rite???(actually its just knowledge)..... its the same thing as my music carreer... i like music but my parents keep on say that if you dont have outstanding results, you will fail in the music business...... AARGH!!!!!!!!!!!!!

why izit so hard 2 choose a course?????? should i go for my interest or my parents wish????????

confused...............................................
