How do i know what school i should go to?

I live in Texas and i am sort of a jack of all trades so im lost in the direction i should take in life, i have thought countless times over a career choice for me to follow and this is what i have narrowed it down to....1. veterinarian (i love animals) 2. mechanic (i love cars) 3. commercial diving (haha im not sure why but i think i would like doing this) also a cook and the list sort of goes on. As you can see my choices have nothing in common and its driving me insane considering that i should go to a school that has options for me to advance in the field that i want. But anyways as for my question, how am i supposed to know what school i should go to if i don't even know what job i want to achieve. (please keep in mind that i have know idea how college works lol) D: if only i was immortal then i would be able to do them all....oh yeah and im freaking out because i will be a senior when school begins and i will have 1 year before the big decision of where to go.
